If you walk around Siam Square, you see a lot of shops that sells clothes, accessories, shoes and bags; and some of the young designers, mostly unknown or undiscovered, sell their designs there. One Shop/wall display that I found interesting is DOKODEMO. They carry Japanese inspired men's RTW, shoes, and accessories.
I find their clothes fascinating. The pieces looks casual and comfortable for a weekend stroll around the city, a style which I am slowly adopting.
