The newly renovated Siam Discovery, located next to Siam Paragon, has an eclectic mix of Asian designer shops and speciality stores, international brands such as Diesel, Apple as well as a Madame Tussaud's museum on the 6th floor.

If you are looking for something more specific on the fashion front, then this place might be worth a look. There is a useful, air-conditioned walkway between MBK and Siam Center.
