Best Preteen Underwear: Top Picks for Comfort & Style

It’s astonishing how many people underestimate comfortable underwear. As adults, we might skimp on quality to save a bit of money, because hey, it’s just underwear, right? That’s all well and fine until a poor quality underwear rides up where it shouldn’t and chafing appears.
At that moment, people really start reflecting on their poor choices. Now, imagine making the same decision for your preteen daughter, who is already agitated enough by pretty much everything. You’d never hear the end of it is a monumental understatement.
Speaking of which, preteen girls are right at the threshold of puberty, and they already feel discomfort. After all, their bodies are about to undergo significant changes, which is why they really need proper preteen underwear.
Quality underwear may not soothe them completely, but at least they won’t add to their troubles. Fortunately, there are plenty of different underwear types that will provide comfort, style, and a much-needed confidence boost for your preteen daughter. With that in mind, let’s have a look at how to pick and choose the ideal pair of undies.
The Qualities of a Great Pair of Preteen Girl Underwear
Quality preteen girls’ underwear is a broad term. It doesn’t just mean that the undies cost more or are made of finer materials. Quality refers to ticking all the right boxes based on your daughter’s needs, and everyone's needs are unique.
Fortunately, you don’t have to pull that information from your kid with a pair of pliers. Every parent knows what their child needs just by looking at them.
Of course, your preteen daughter may disagree because apparently, you know nothing about her, you don’t understand her, and all the other stuff kids say when they suddenly become self-conscious due to raging hormones.
This, too, shall pass eventually, but in the meantime, you’ll have to find a common ground with her when shopping for a bra, panties, or both. In order to help you out, here are some of the things you should look for when choosing an ideal pair of underwear.
Soft, Breathable Fabric
The quality of fabric determines how comfortable your daughter’s underwear will be. As you may already know, there are literally a myriad of different materials and fabrics used in the textile industry. However, not all of them are suited for your preteen.
For example, if your kid is showing the first signs of puberty, chances are that she’ll have sensitive skin, extensive sweating, and body acne, aside from hair growth.
That said, fabrics such as cotton, bamboo, and modal are extremely soft, breathable, and moisture-wicking, which means underwear made from these materials is ideal for preteens going through puberty.
Style Over Substance
If a preteen likes what she sees, she’ll go for it. Aesthetics matter more to young girls than anything else. Therefore, you have to consider the cute factor too.
Fortunately, the vast majority of underwear on the market today combines both style and practicality, so you won’t have much difficulty finding a pair of undies that are super comfortable, functional, and look great at the same time.
Proper Sizing
Kids grow fast, faster than we realize. One day, your daughter is just a kid; the next, she needs a bra, go figure. Buying underwear for kids who are growing seems like an uphill battle.
Well, all you can do is be tactical about it. For example, opting for adjustable padded bras means that you won’t have to replace them as soon as your kid grows an inch or two.
Sizes like 8/10 mean that the pair of underwear is designed to fit girls between the sizes of eight and ten. In other words, you’re good for a longer while.
Added Comfort
Attention to detail is what makes preteen girls’ underwear stand out from the rest. Most manufacturers know that young girls who are about to enter puberty or have already entered it can be extremely sensitive to any stimuli.
To make things easier for them, many brands have removed seams, labels, and other details that can further irritate the skin or make girls uncomfortable. This type of attention to detail is what you should look for in a pair of preteen undies.
Best Preteen Underwear Options for Style and Comfort
Now, it’s time to choose an ideal pair of underwear for your tween. Easier said than done. As mentioned before, there are many brands that combine both style and comfort, but with so many options out there, where does one even begin?
Fortunately, we’ve prepared a small and practical guide that will help you make heads or tails of of the options available for tweens. Our guide will point you in the right direction, so all that remains is to find something your daughter will absolutely love.
Briefs Underwear
Briefs are an embodiment of comfort in the world of undies. They are practical, offer good coverage, and can fit well under basically any outfit. They are simply perfect for preteens due to the fact that most undies are made out of natural fibers such as cotton or modal.
As you may already know, organic cotton is very soft, extremely durable, and one of the best moisture-wicking fabrics in the world.
As far as style goes, briefs slightly resemble the good-old tighty-whities or granny panties, which might indicate that your daughter may not find them appealing.
However, the style of modern briefs for young girls has been perfected over the years, and there are adorable pieces that even the pickiest of girls couldn’t say no to.
Key Features:
-
Cotton briefs are perfect for sensitive skin, due to the hypoallergenic properties of cotton.
-
Briefs are designed to provide comfort above all else, which is why there are seamless models with no labels or accessories whatsoever.
-
Extended coverage is great for shy girls, and the extra fabric is excellent for fitting in pads if your daughter is on her first period.
Bikinis
Bikini undies are probably the most sought-after model among preteen and teenage girls. These panties are very stylish, but at the same time, they also offer modest coverage.
Unlike briefs, bikinis have higher leg-cut openings, wider side cuts, and a lower waistband. In other words, they are more flexible and liberating in terms of movement.
Key Features:
-
Very stylish undergarments that come in various sizes, colors, and styles.
-
Often made from different fabrics or blended materials, so keep an eye out if your daughter has any allergies to specific materials.
-
Although a bit daring, bikinis offer a great boost in confidence and self-esteem. They can be worn for any occasion and fit well under anything your daughter has in her wardrobe.
Boyshorts
Inspired by the boxers boys often wear, boyshorts are the girl variant of boxers, redesigned to suit the needs of your preteen.
In terms of coverage, boyshorts cover everything and ensure everything stays where it should be. This makes them ideal undies for active girls who are into sports or any other kind of physical activity.
Key Features:
-
Very snug, very fitting, so that they can be easily worn under skirts or school uniforms.
-
Not ideal for everyday wear, a lot of coverage can feel overwhelming, even though most boyshorts are made out of breathable materials.
-
Boyshorts can contain spandex and elastane, which makes them more snug. And even if your daughter has sensitive skin, boyshorts will offer just a touch of stretch, which makes them the perfect choice.
Hipsters
Hipsters combine the best both briefs and bikinis have to offer. They are a perfect blend of the two, providing comfort and coverage while also providing style and flexibility.
They fit perfectly on the hips, hence the name. Among all panty models, hipsters are the most versatile.
Key Features:
-
Hipsters come in various styles, such as casual, lacework, no panty line or seamless, and printed with unique patterns, aside from a plethora of colors.
-
Hipster panties are designed to accommodate any body type, which is why you can opt for high-waist, mid-waist, or low-waist hipsters with either full or medium coverage.
-
Hipsters are made from various fabrics, so again, keep that in mind if your daughter has sensitive skin or allergic reactions to specific materials.
Things to Keep in Mind When Shopping for Preteen Girl Underwear
As mentioned before, your kid will likely zoom in on the style and disregard everything else. Not saying kids are unreasonable or disobedient, it’s just that they are wired differently, especially right before puberty kicks in.
It’s up to you to point out that other factors like comfort, flexibility, durability and others are just as important as style. So, make shopping for underwear a journey, not an obligation.
For example, if you’re already looking for undies, why not look for a matching bra, as well? A nice training bra will really complement whatever your daughter decides to buy. But, hold on, when do girls start wearing training bras?
Well, although not necessary, it’s preferable for girls to start wearing one as soon as they start to develop. That said, thelarche, also known as breast budding, is one of the first signs of pubertal development.
Wearing a training bra is ideal in such situations. The main reason is that training bras offer slight support with no underwires or paddings. They are simply comfortable, cute tops that go very well with any type of undies.
While you’re at it, it’s always a good idea to keep an eye out for fabrics and materials. Preteens who will soon enter puberty, if they haven’t done so already, require gentle materials so that their skin isn’t irritated further. Here are a few examples of different fabrics that are perfect for preteen underwear.
-
Cotton - Extremely durable, soft, breathable, and moisture-wicking.
-
Bamboo - More moisture-wicking and softer than cotton. However, it tends to lose shape after a number of washes.
-
Modal - Better than any other fabric regarding softness, breathability, and moisture-wicking. Unfortunately, it’s more expensive than the rest.
-
Silk - Very smooth, very comfortable, and most importantly, very delicate. But, like modal, silk undies are expensive.

FAQ:
What size underwear does a 12-year-old wear?
That entirely depends on specific measurements like hip size, waist size, height, and weight. What’s more, different apparel brands have different measurement charts, so you really need to look at those and compare them. In most cases, those size charts vary slightly, but differ nonetheless. So, for example, if your 12-year-old is size 10 at one brand, she may be size 11 at the other.
What type of underwear should a 15-year-old girl wear?
The most popular types of underwear among young girls in general are hipsters and bikinis. These undies are both practical and stylish, offering everything a young girl could possibly need. Whether girls go for hipsters or bikinis comes down to personal preferences.
What kind of underwear does Gen Z wear?
Hipsters, bikinis, bras, bralettes, you name it, they wear it. Gen Z is more environmentally conscious and socially responsible than previous generations. As such, they won’t buy anything from brands if it’s not inclusive or responsibly sourced.
Is 12 underwear enough?
Considering the fact that young girls should switch panties daily, 12 pairs should suffice. However, more is always better, especially since you can sync washing cycles without risking not having underwear until the batch you just washed dries out.
