What Is a Training Bra?

A training bra is a type of bra designed for girls who are just starting to develop breasts. Training bras are usually smaller and less structured than regular bras, and are often made of soft, stretchy material to be more comfortable for young girls. They are also usually worn for comfort rather than for support. Training bras can help a girl feel more comfortable and confident as she goes through the process of developing breasts, and can also help her get used to wearing a bra. Some girls may not need or want to wear a training bra, and that is perfectly normal as well. Ultimately, the decision to wear a training bra is a personal one that should be made by the girl and her family.

There are several types of training bras. To read about the different types and which one might be best for your child, read Types of Girls' Training Bras.

A training bra should fit snugly but comfortably around the chest. It should not be too tight or too loose. The band of the bra should be parallel to the ground all the way around the body, and should not ride up in the back. The straps of the bra should be adjusted so that they do not dig into the shoulders, but should not be too loose either. The cups of the bra should completely cover the breasts and should not gap or spill over.

If a girl is having trouble finding a training bra that fits well, it is a good idea to try on a few different styles and sizes to find the one that works best. It is also a good idea to get fitted by a professional bra fitter or to ask a trusted adult for help in finding a bra that fits well. Wearing a bra that fits well can help a girl feel more comfortable and confident, and can also help prevent problems such as chafing or discomfort.

What Age Do Most Girls Need a Training Bra?

There is no set age for when girls need to start wearing training bras, as every girl is different and develops at her own pace.  Some girls may start developing breasts as early as 8 years old, while others may not start until they are much older. Girls may also start wearing training bras at different times depending on their level of comfort with their changing bodies.

It is generally recommended that girls start wearing a training bra when they begin to show signs of breast development, such as the appearance of breast buds or nipples that are starting to protrude. This can be a good time to start wearing a training bra to get used to the feeling of having something covering the breasts, and to provide a small amount of support. However, if a girl does not want to wear a training bra, it is important to respect her wishes. Read My Daughter Won't Wear a Bra

Choosing the right training bra offers the comfort and confidence a girl needs as she grows. There are various types available, each designed to meet different needs and preferences:

Padded Bras

  • Our Top-Pick: The Bleum Petal Padded Bra is a fantastic choice for everyday wear. It offers light padding and soft fabric for a seamless look under any outfit. 

Sports Bras

Designed to offer maximum support during physical activities, sports bras are typically made from breathable fabrics. This keeps girls comfortable and dry during exercise. They also often feature a racerback design to provide additional freedom of movement.

Soft Cup Bras

For gentle support without the use of underwires, soft cup bras are a great choice. They are ideal for young girls who are just starting to wear bras and want something that feels natural and unobtrusive. 

  • Our Top-Pick: One excellent option from Bleuet is the Iris Soft Cup Bra. This soft cup pullover bra offers optional light padding for extra support and coverage, ensuring comfort and confidence for growing girls. Available in various colors, it’s perfect for any wardrobe.

Camisole Bras

Camisole bras blend the coverage of a camisole with the support of a bra. They are an excellent option for girls who prefer more coverage or who are looking for a smooth look under their clothes. These bras often feature built-in bras or shelf bras for added structure.

  • Our Top-Pick: The Bleuet Camisole really stands out in this sense. Whether you want to layer it under your clothes or wear it alone, it’s a snug and comfy fit for girls who want a bit more modesty.

  • Discuss what she feels comfortable with and what her preferences are. Some girls may prefer more coverage, while others might want something lightweight and simple.

  • Take her measurements accurately to ensure a proper fit. Refer to the step-by-step guide below.

Step-By-Step Guide to Measuring for a Training Bra

Measuring for a training bra is important for achieving maximum comfort, support, and confidence. To get the right fit, simply follow these steps:

1. Prepare for Measuring

  • Ensure the girl is wearing a lightweight, non-padded bra or a fitted camisole.
  • Use a soft measuring tape for accuracy.

2. Measure the Band Size

  • Wrap the measuring tape around the ribcage, just under the bust. Ensure the tape is snug but not tight and is parallel to the ground.
  • Note the measurement in inches. This is the band size. If the measurement is an odd number, round it up to the nearest even number.

3. Measure the Bust Size

  • Wrap the measuring tape around the fullest part of the bust, making sure it is level and not too tight.
  • Note the measurement in inches. This is the bust size.

4. Calculate the Cup Size

Subtract the band size from the bust measurement. The difference in inches determines the cup size:

  • 1 inch = A cup
  • 2 inches = B cup
  • 3 inches = C cup
  • 4 inches = D cup

For example, if the band size is 28 inches and the bust size is 30 inches, the difference is 2 inches, resulting in a B cup.

5. Understanding the Fit

  • Band: The band provides most of the bra's support, so it should fit snugly around the ribcage without riding up or being too tight.
  • Cups: Properly fitting cups should fully encase the breast tissue without any spillage or gaps. This will prevent discomfort or shifting during wear.
  • Straps: Straps should be adjusted so that they stay in place without slipping off or digging into the shoulders.
  • Comfort Check: Move around and perform some basic movements (like raising arms or bending over) to ensure the bra stays in place and remains comfortable.

 

Care and Maintenance of Training Bras

To get the best out of your training bra, proper care and maintenance is essential. Take a look at these tips to ensure they last longer and remain comfortable and supportive throughout, along with tell-tale signs they need replacing:

Washing Instructions

Hand Wash Whenever Possible

Hand washing is the gentlest way to clean your bras and helps them maintain their shape and elasticity. Use cold water and a mild detergent specifically designed for delicate fabrics.

Use a Lingerie Bag

If you prefer to use a washing machine, place your bras in a lingerie bag to protect them from getting tangled or stretched. Set the machine to a gentle cycle with cold water.

Avoid Harsh Detergents

Opt for mild, fragrance-free detergents to prevent irritation and preserve the fabric’s integrity. Avoid bleach or fabric softeners, as they can damage the material and reduce the bra's lifespan.

Air Dry

Lay your bras flat to dry on a clean towel or drying rack. Avoid wringing them out or using a dryer – the heat can break down the elastic fibers and cause them to lose their shape.

More Care Tips

Rotate Your Bras

Avoid wearing the same bra two days in a row. Rotating them gives the elastic time to recover and helps maintain their shape.

Store Properly

Store them in a drawer with ample space, avoiding crushing or folding the cups. It’s best to use drawer dividers or lay them flat to keep their form.

Signs It's Time to Replace a Bra

  • Loss of Elasticity: If the band or straps have become loose and no longer provide proper fit and support.
  • Fraying or Pilling: Visible wear and tear, such as fraying edges or pilling fabric.
  • Stretched-Out Straps: If the straps are no longer adjustable or keep slipping off the shoulders.
  • Faded or Discolored Fabric: The fabric has become faded or discolored over time from washing and wear. 
  • Changes in Fit: If the bra no longer fits well due to changes in body size or shape.
