While I love the cotton summery frocks that end above the knee, I think all girls must have one of the frilly lacy variety as well. After all they are unlikely to be able to wear them later in life.
Discovered a little shop called Little Flowers or some such tucked across Just Casuals on Sterling Road, Chennai which specialises in Frocks from Thailand. Really pretty , not over the top dressy stuff.
There is also a customised frock shop in Kormangala opposite Not Just Parathas in Bangalore.
