How to Choose Your First Bra: A Complete Guide
Getting your first bra is a big moment. It can feel exciting, empowering, and maybe even a little nerve–racking, all at the same time. Whether you're buying your very first bra or you're someone helping a younger person through the process, we're here to make it feel simple.
At Boux Avenue we believe finding your first bra should be a positive experience, and is most certainly not something to feel embarrassed about. Our bodies are ever changing, and everyone's journey looks a little different. Whether you're shopping online or visiting us in store, we're here to help you feel confident, comfortable and supported every step of the way. In this guide, we'll walk you through everything you need to know, from when to start wearing a bra and how to measure for the right fit, to the best styles to choose and the difference between a first bra and a training bra.
When Should You Get Your First Bra?
While lots of girls may get their first bra somewhere between the ages of 8 and 13, earlier or later is completely normal. Everyone develops at their own pace, so try not to compare your journey with anyone else's. Some people start noticing changes in primary school, while others don't need or want a bra until their early teens. However your body changes, there's no rush - and there's certainly no "perfect" age at which to start. Instead of focusing on your actual age, it may be more helpful to think about whether you feel ready. Some signs that it might be time for your first bra include:
- You're starting to notice breast buds or developing breast tissue.
- You'd like a little extra coverage underneath your school shirt, PE kit or favourite tops.
- Light support feels more comfortable during everyday activities.
- You've started thinking about wearing a bra because your friends are, and you'd like to try one too.
Whether you're shopping for a younger girl or a teen, the best first bra is one that feels soft, comfortable and easy to wear. If you're not sure where to begin, we always recommend starting with an in store fitting. Our friendly experts are specially trained to fit bras and to make the whole experience feel relaxed, welcoming and reassuring. They'll help you find the right size, explain which styles will feel most comfortable, and take all the guesswork out of choosing a first bra - so you can simply enjoy the experience.
You can book a bra fitting at your nearest Boux Avenue store, where our expert fitters will help you find the perfect fit in a comfortable, private setting. If you can't make it into store, don't worry. You can also find your bra size using our online fit quiz from the comfort of home. While nothing beats an in store fitting for a first bra, our quiz is a great alternative if visiting a store isn't possible.
Why Is Choosing the Right First Bra Important?
Choosing your first bra is about finding something that gives you the support and coverage you need while feeling so comfortable that you almost forget you're wearing it. As your body begins to change, the right bra can help you feel more at ease and confident day to day. A great fit offers gentle support, sits smoothly under your clothes and helps you feel comfortable whether you're sitting in class, running around with friends or relaxing at home. Most importantly, it should feel like you!
Every body develops differently, so your bra needs will naturally change over time too. A soft, seamless bralette might be exactly what you need to begin with, while a few months or years later you may feel ready for something with a little more structure or support. That's completely normal.
You might even find that different occasions call for different styles. A comfortable everyday bra for school, a seamless style for under fitted tops or a sporty option for PE can all become part of your collection as you grow. Whatever stage you're at, there's a style designed to help you feel comfortable, confident and supported.
How to Measure for Your First Bra
Before you shop for your first bra, it’s important to know your size. Here’s a simple guide to measuring yourself at home:
- To measure your band size: take a soft measuring tape and measure around your ribcage, just under your bust. Make sure it’s snug but not tight. The tape should be parallel to the ground.
-To find out your cup size: measure around the fullest part of your bust, keeping the tape comfortably in place.
-The difference between this and your band measurement will tell you your cup size.

First Bra vs Training Bra
If you've heard the term ‘training bra’, you might be wondering how it's different from a first bra. The simple answer is: a training bra and a first bra are essentially the same thing. Both are soft, wire-free bras designed for early breast development, offering light support and coverage while you get used to wearing a bra. These days, the term ‘training bra’ isn't used as often as it once was. Instead, you'll usually see styles described as bralettes or non-wired bras, but they're designed with exactly the same goal in mind: helping you feel comfortable and supported as your body changes.
A soft, non-wired bra is often the perfect place to start, while a comfy bralette is another brilliant everyday option. Both offer gentle support without the structure of an underwired bra, making them ideal first choices for many first time bra wearers.
What Makes the Best First Bra?
Finding the perfect first bra is all about comfort, support and fit. Rather than focusing on what's fashionable, think about what feels good to wear every day. The best first bra should feel soft against your skin, fit comfortably and give you just the right amount of support as your body begins to change.
When you're choosing your first bra, here are a few things to look out for:
- Soft, breathable fabrics such as cotton or microfibre, which feel gentle against sensitive skin and are comfortable enough for all-day wear.
-Adjustable straps, so you can tweak the fit as you grow and make sure your bra feels secure without digging in.
-Seamless designs that sit smoothly under school uniforms, T-shirts and everyday outfits without showing through.
-Wire-free comfort, which is often the best place to start if you're new to wearing bras, offering gentle support without feeling restrictive.
For a relaxed first fit, it's hard to beat a soft bralette. Lightweight, flexible and easy to wear, they're perfect for everyday comfort. If you'd like a little more support while still keeping things soft and comfortable, a wire-free bra is another brilliant choice. When it comes to colours, you don't have to overthink it. Neutral shades like white, black or nude are versatile staples that work well under school uniforms and lighter-coloured clothing. Once you've found a style you love, you can always have fun adding brighter colours or pretty prints to your drawer too.
Remember, your body won't stay the same forever. Throughout your teen years, it's completely normal for your size and shape to change, so it's worth checking your fit every so often. A bra that felt perfect six months ago may no longer be the best fit today, and that's simply part of growing up.
First Bra Checklist
Shopping for a first bra doesn't have to feel complicated. Here's a handy checklist to help you remember the essentials before you choose.
Do:
✓ Choose soft, wire-free styles that feel comfortable from the moment you put them on.
✓ Look for breathable fabrics like cotton or microfibre for all-day comfort.
✓ Pick adjustable straps so you can find the perfect fit and adapt as your body changes.
✓ Book a bra fitting in store for the best first-bra experience. If you can't make it into a store, you can always find your bra size at home with our online fit quiz.
✓ Start with versatile colours like white, black or nude that work well under school uniform and your favourite everyday outfits.
Don't:
✕ Feel like you have to wear a bra just because someone else is.
✕ Jump straight to heavily padded or push-up styles when you're choosing your first bra.
✕ Guess your size based on a friend's or assume you'll be the same size as someone your age.
✕ Expect one bra size to last forever. Your body changes throughout your tween and teen years, so it's a good idea to check your fit regularly.
Choosing your first bra should be an exciting milestone, not a stressful one. Whether you're buying one for yourself or helping someone else choose their first bra, the most important thing is finding a style that feels comfortable, supportive and helps build confidence as your body grows and changes. Remember, there isn't one "right" age to start wearing a bra, and there isn't one perfect style for everyone either. Every body develops differently, which is why taking the time to find the right fit is so important.
