I asked my younger cousin who is 23 what she wants for her birthday, and she said "cute clothes." I am thinking a dress or a coat with girly bows or ruffles. Do you know a designer or a store sells lots of cute girly clothes?
aquahot, top shop! I am your cousin's age and I love bows and ruffles so I know where she's coming from. I buy stuff from TopShop from time to time. Price is very agreeable and the styles are very cute. The size 2(their smallest size) is"okay" on me..could be a bit tighter, but if you cousin is small too, I'd recommend that brand!
I picked out some things your younger cousin might like!
