Myntra is among the few sites which I always check while shopping for clothes online. The best part about Myntra is the variety of options that are available.
It contains all the major brands and sometimes you can get them for a very good price during offers. My personal experience has been decent with them.
I bought a couple of shirts and a pair of jeans during there shopping festival and they all where very good. Just one bag which I ordered turned out to be different then what I thought, but it was easily replaced and I got my money refunded to my bank account within 10 days. Such experiences increases your faith in online shopping. A good place to shop clothes.
