clothes for 1mth baby gal, there are lots of them in stores from the high-end stores to neighbourhood shops.
Just go with the budget which you have set and hit the respective stores. More options at United Sq and Paragon Mall (if you are into branded ones) otherwise, average-familiar stores like Metro, Kiddy Palace, Isetan, etc do sell nice girly dresses.
Dressing her up with Minnie Mouse influences would be fun too. She'd look adorable, i bet.
