Not really teen ( mire pre teen), dd1 is 11 in a couple weeks, she has been wearing crop tops for a year but is growing fast so will be heading a bra. She is quite slim and small for her age ( apart from her boobs which are growing fast ). Where's the best place to buy her first proper bra? Also she has dyspraxia and Aspergers, she is likely to struggle with doing it up? Would a sports type bra be better?
