With two Bay Area locations (one near South Park in San Francisco, the other on College Ave in Berkeley), Jeremys stocks a lot of high-end designer fashions and sells them cheap. That's because they stock end-of-season leftovers, slightly damaged display goods, and customer returns.
I've seen top brands here such as Prada, Marc Jacobs, and Manolo Blahnik. Ok, so you still might not fork over $300 for something that once sold for $1,000 retail but it's nice to know that you can. For those who would still balk at those prices, I've also seen less expensive brands such as J Crew, Anthropologie, and Agnes B.
Be forewarned. You definitely have look through your purchases carefully before you buy. Sweaters may have holes in them. Zippers may not work properly. Pant seams may be ripped slightly. The size selection isn't always the greatest either. You really need to spend time to dig. But when you find that one treasure cheap, you'll be glad that you did.
