need to buy a formal wear for my 10 year old girl. blazer, shirt and skirt for a formal event from school. any suggestions from where to buy?

i think you can take a look at Shoppers Stop. you can check in the women's section and go for the XXS, XS or S size. i am not sure about formals for kids, but Shoppers Stop has very good formals and some of the smaller sizes can easily fit a 10 year old.
