Well in India, you could try Rajesh Pratap singh and Gaurav Gupta, there probabably the few avant garde designers we have.

hi, if you are planing to make a trip to singapore, you could try these brands, Abyzz by Desmond Yang, Woods and Woods (in a cafe/boutique called 'Front Row'), Baylene, Rabbithabit, POSSE.

However, I won't say they are so avant garde but it's the most avant garde I can think of in terms of Singapore designers.

However, in my opinion, Thailand is great for avant garde items!

Have fun!
