Winner's is a great place to go if you have enough time to go through racks of clothes and really hunt for a steal of a deal. This Winner's especially has some really great clothes - Earl Sewn Jeans, Ralph Lauren Boots, Jones New York Sweaters, I could go on.
The thing about Winner's is that you can't really run in and grab something and go. Things are organized by size, not designer, so you'll have to sort though the racks to find your size. Also, as is common with designer label discount stores, you'll have to sort through a ton of ugly crap.
But on a rainy saturday, there's nothing better than spending the afternoon getting yourself a cheap wardrobe. And Winner's is the best place in the city to do it.
