Tweens middle school wearing training bras.

According to a survey by The Mental Health Foundation, 46% of girls reported that their body image causes them to worry ‘often’ or ‘always.’ [1] This makes choosing the right training bra an important step in helping them feel confident and comfortable during this stage of their development.

That’s where we step in. In this guide, we’ll walk you through everything you need to know about training bras for tweens in 2024. 


What Is a Training Bra?

A training bra is a garment designed specifically for tweens who are just starting to develop breast buds during middle school. These styles are typically made from soft, stretchy materials to provide comfort and modesty without the need for underwires or heavy padding. 


Why Tweens Need Training Bras During Middle School

During puberty, tweens in middle school might need a training bra for several reasons:

  • Comfort and Support: As girls go through puberty, their bodies change, and their breasts begin to develop. To this end, a bra provides the necessary coverage to accommodate these changes. Plus, they help to prevent any discomfort during daily activities.
  • Modesty: They offer an extra layer of coverage under clothing, which can help with feeling more secure, especially during physical activities or in social situations.
  • Body Confidence: Wearing one can help boost body confidence by providing reassurance and promoting a positive body image. It helps them feel more relaxed with their changing bodies and reduces self-consciousness.
  • Preparation for Future Bras: They are a gentle introduction to wearing bras, making the transition to a more structured design smoother as they continue to grow and develop.
