What Does a Training Bra Do? A Mom’s Guide to Supporting Your Daughter

What does a training bra do? As your daughter approaches puberty, you might find yourself wondering this exact question. Training bras provide gentle support and great coverage for girls who are beginning to develop breasts, helping them feel more comfortable and confident during this important transition. Want to know more about how they can support your tween’s journey?

Understanding Training Bras

Training bras are specially designed undergarments for tweens and young teens in the earliest stages of breast development. Unlike regular bras, they’re:

  • Super lightweight and soft
  • Made with stretchy, breathable fabrics
  • Free from uncomfortable underwires
  • Designed with minimal or no padding
  • Built for comfort rather than significant support

When breast buds first appear, many girls experience tenderness and sensitivity. Proper support can help girls at the early stage of breast development maintain physical activity comfortably.

What Age Should A Girl Start Wearing A Training Bra?

Every girl develops at her own pace. Some might show signs of breast development as early as 8, while others might not until 13 or 14. Here are some signs your daughter might need a training bra:

  • Visible breast buds or nipple development
  • Complaining about tenderness or sensitivity
  • Feeling self-conscious about changes
  • Wanting extra coverage under shirts
  • Mentioning that her friends have started wearing bras

There’s no wrong time to start wearing her first training bra if your daughter feels ready. The right moment is when she needs that extra bit of comfort or privacy. 

What Is the Point of A Training Bra?

Training bras serve several important purposes:

  1. Physical comfort – They provide light support and protection for sensitive breast tissue
  2. Emotional confidence – They help girls feel less self-conscious about their changing bodies
  3. Smooth appearance – They create a more uniform look under clothing
  4. Activity support – They keep everything in place during sports and physical activities
  5. Preparation – They help girls get used to wearing bras before needing more supportive styles

Interestingly, not wearing a training bra or proper support can lead to discomfort and embarrassment, which might discourage girls from participating in sports. For instance, a study found that many girls avoid sports due to breast-related issues, such as pain and embarrassment, highlighting the importance of proper breast support during physical activities. 
Ensuring your daughter has the right bra can make a big difference in her comfort and confidence, whether she’s playing sports or just hanging out with friends.

Types of Training Bras

There are several bra styles to choose from:

Three types of bras displayed: a lightly padded training bra, a bralette, and a sports bra.

Bralettes

Soft, stretchy bras without clasps or adjustable features – perfect for absolute beginners.

Sports-Style Training Bras

Similar to sports bras but with less compression, these offer slightly extra support for active girls.

Camisole Bras

Training bras built into camisole tops, providing seamless coverage and extra discretion.

Lightly Padded Training Bras

Offer a bit more coverage and can help prevent show-through under lighter shirts. However Suyiyi suggests that girls aged around 12 to 15 with a bust size comparable to a lemon should consider wearing padded bras.

 

Different styles work better for different body types and activities. The Journal of Women’s Sports Medicine suggests that proper fit is more important than style for comfort. 

How to Choose the Right Training Bra

Finding a comfortable training bra that fits properly makes all the difference:

  • Proper fit – Should be snug but not tight, with no gaps or digging in
  • Comfortable fabric – Look for soft, breathable materials like cotton blends
  • Perfect amount of coverage – Should cover the entire breast bud area
  • Right style – Consider your daughter’s preferences and activities
  • Easy care – Machine washable fabrics make maintenance simple

Many girls benefit from trying different styles to see what feels most comfortable. Suyiyi offers a range of training bras specifically designed for growing girls that meet all these criteria. Or check our guide to find the best starter bras for girls.

  • Keep it positive and matter-of-fact
  • Frame it as a normal part of growing up
  • Let her know that every girl develops differently
  • Give her choices in the selection process
