Choosing your first bra

There's no right time. Start when you feel uncomfortable without one, when you do sport, or simply when you want to.

• Measure under your breasts: that's your band size.
• Then measure at the fullest part: the difference gives your cup size.
• Always try it on in the shop.

• Soft cotton with no seams.
• The band sits flat and doesn't ride up your back.
• The straps don't dig in or slip.
• Pick a separate sports top for sport.

Your size will change as you grow, so don't buy a lot at once. Going with your mum, sister or a friend can make it easier.
