So am I able to come in and just sell my cloths? If there of course washed and fairly new? How much would I be getting in terms of quality,brand, size, condition, etc?

You are able to sell your clothes fairly easily. They usually always take in season things but will also consider other things. You wouldn't be getting much of your money back though. If you are thinking of going in, make sure your stuff is in a bag or a box (they count per bag). They also offer cash or in store credit which is a bit more.

As long as they are in season. But sometimes they can have a pretty full inventory. You don't get too much back compared to some other consignment shops. So if your goal is to get more money in return, this wouldn't be the place unfortunately.
