When should you buy your daughter’s first bra? How to choose the right size, what type to pick, and how to talk to her about puberty.
Buying a first bra is a meaningful step — it offers physical support and helps build confidence, especially during PE classes. This guide will help you understand when to make that purchase, how to find the right size, fabric, and style, so that wearing underwear feels comfortable and natural.
A well-fitted bra is the key to comfort, health, and a flattering silhouette. A band that’s too tight can cause back pain and restrict movement, while one that’s too loose fails to support the bust and makes clothes sit awkwardly. It’s estimated that over 70% of women wear the wrong bra size. Here’s how to measure yourself at home in just a few simple steps and find your perfect fit.

To accurately determine your bra size before placing an order, take your measurements and compare them with the size chart provided.
Use a measuring tape while standing upright and breathing naturally.
1. Measure under the bust while standing, without wearing a bra, keeping the tape snug but not tight.
2. The measuring tape should be placed directly under the bust, level across the front and back.
3. Subtract 3 cm from the measured value and round it down to the nearest lower band size.
4. For example, if your underbust measurement is 81 cm, subtract 3 cm to get 78 cm — you should choose a bra with a band size of 75.
Measuring the bust:
1. Measure your bust while wearing a soft, non-padded bra that gently lifts your breasts.
2. Place the tape around the fullest part of your bust, keeping it level at the front and back. The tape should be slightly taut but not tight.
3. Compare your results with the size chart.
