The closest building to the clothing stall is the tavern and there is a weapons stall right by it. I think the stall has regular items in with it. However if you wanna go back to the Market (I can't remember the name of the town.) There are two clothing stores in that town, one is next door to blacksmith and across from the hair stylist shop, that one is a female character clothing shop I think. And the other is down the little you have to turn down to get to the lower part of town, that's the male clothing shop. That one is on the left side. The best thing to look for is a sign with a needle and thread.
