The best training bras (aka junior bras) make a comfortable, easy transition to adult bras when an undershirt just doesn’t cut it anymore. Let’s face it, puberty is hard. There are zits to battle with endless acne treatments, the task of learning to shave, plus all the other physical (let alone emotional) changes a maturing body goes through. The journey to adulthood can be downright awkward, which is why finding the right training bra will keep your tween comfortable and confident. Junior bras don’t just provide some support, but really their primary job is to conceal and cover. Whether it’s a transparent training bra that’s invisible under clothes or a pretty, delicate bralette for girls, this guide will help you find the perfect training bra for. your kiddo.

Around the time that 90s cartoons were still on the air, we remember (not very fondly) our first experiences with training bras. Stiff white polyester with clasps that felt like only a magician could hook. And don’t get us started on how they made our budding chest look bigger (and more cone-shaped – and not in a not a cool Madonna way, either). So mortifying! Lucky for girls now, those are the training bras of their mother’s (ahem, our) past. But luckily, today’s best training bras are soft, moveable, easy to slip on, and actually cute.

Are training bras really necessary?

According to Pediatrician and puberty expert, Dr. Cara Natterson, while training bras aren’t necessary, they can be very beneficial for tweens! Dr. Natterson is also the co-founder of OOMLA, author of the best-selling series The Care and Keeping of You, and a fellow Mama.

“New breast tissue can be exquisitely tender, so having some material between the skin and a tee-shirt or sweater makes a big difference for some girls,” Dr. Natterson says. “And when something or someone knocks into growing boobs – like a ball to the chest during sports or an accidental elbowing while hanging out with friends – a bra can reduce the ouch factor.”

Dr. Natterson mentions that there are great emotional benefits to training bras as well. For one, minimizing obvious body changes can do a lot for a tween.

“If girls feel better about themselves because their new curves aren’t quite as obvious, that self-esteem bump should be recognized,” she adds.

When should my daughter start wearing a bra?

When exactly to introduce a training bra can vary, but the average age tweens begin wearing bras is around 11-years-old, which is when the early stages of puberty usually begin. But remember, everyone is different! Some tweens may need them much earlier (sometimes as early as age 7), and others may not need one until they’re teenagers. Remember to listen to your tween and keep an open dialogue so they know they can ask when they think it’s time!

Which bra is best for tweens?

A first bra should make them feel comfortable and confident. For maximal comfort, Dr. Natterson suggests looking for training bras made from super soft, cotton-based fabric (synthetic material can hold onto odors and no one wants that!).

“The straps should fit across the shoulders without digging in or falling off. Look for smooth, stretchy elastic to avoid irritation by clips, clasps, or rough edges,” Dr. Natterson adds. She also suggests steering clear of sewn-on bows or anything else that will make the bra noticeable through clothing.

“Perhaps most importantly, the bra should gently compress growing breast tissue without binding it, helping to minimize sensitivity in the area and maximize confidence,” she explains. “Big bulky pads don’t do the job here…the ideal first bra is one that wraps gently around the chest.”

For a tween on the shier side, finding a transparent training bra that blends seamlessly under t-shirts can make all the difference. But other young adults will feel more confident in something that celebrates their femininity, like a lacy bralette for girls. Got an athlete in your house? There are also fantastic options for those sporty kiddos who are always ready to run. Regardless of the junior bra style you’re looking for, one thing’s for sure: Your preteen will feel more comfortable in their own skin when you find the best training bra for them.

It smoothed her front without bulk so she’s not self-conscious. Some clothing she has was on a thinner side, so it also eliminated the need for an undershirt. I feel like her posture got better because she’s not slouching trying to hide, too.” Yes Mama, you can help give her the coverage and confidence to stand up tall and tackle the day.

Calvin Klein Girls Modern Cotton Bralette

These U-shaped bralettes are great for anyone, but they’re especially ideal for pre-preteens just looking for something simple and casual to wear under shirts. “Calvin Klein is the best,” reviews one mom on Amazon. “I bought two of these packs for my daughter who likes her shirts a little long and baggy. She doesn’t like the inverted V-shape tops on a lot of the training bras — looks too grown up — and those teeny straps have a way of breaking and twisting and being annoying. I love Calvin Klein bras for myself and was so happy to find these. She wants me to buy her four more so she can have one for every day of the week.” This breathable bralette from CK is the ultimate in cotton comfort for tweens who aren’t fans of all the frills. Reminiscent of the CK underwear that has been cool since the 1980s, this Calvin Klein bralette sports the ever-cool wide logo band that’s just like Mom’s.

Very well-made and comfortable — just right! We would highly recommend it.” Not only will she feel extra special with the added touch of lace down the back, but the soft seamless design sports a special ruched bust to guarantee a flawless fit.
