Buying bra for someone else's kid, ok or not?

My 11 year old niece has started to develop breasts. I don't know her mom because she lives in Malta but I've been in my nieces life since she was 5.  I remember having to ask my mum to take me bra shopping for my first bra and it was so awkward and embarrassing, I hated it. My friends moms had all given them bras and I felt really uncomfortable.
