This marketis huge and colorful. There are hundreds of stalls with jackets of famous brand, more clothes and of course food. This is one of not too many places in Vietnam where you can buy strawberries.
Damnoen Saduak is around an hour drive from Bangkok and is one of the biggest and most popular ones. Take your time exploring, be patient and look for vendors more inside rather on the edges who try to sell you expensive souvenirs. The deeper you go the nicer locals you'll encounter too.
This market is truly big and there are many stalls with various products but it feels somehow empty. Lazy sellers, people just passing by, quiet chit chats. Nice to visit and see anyways, maybe you'll find some nice pieces here.
One of the biggest market I've been to in Vietnam. 3 floors of all kinds of things you might not even think they have starting with face masks and ending on fabrics. Can get lost too. Some sellers say "no-no" the second they see you though, might be because you're a tourist and they just don't wanna deal with you.
