I browse Net-a-Porter every week, mostly just to dream about owning any of the Mulberry shoulder bags. I came across Mr. Porter, the men's store that sells brands like Lanvin, Burberry, YSL, Gucci, and Louis Vuitton.
The man of my dreams wears clothes like this, but the Henry Cavills and Brad Pitts are far and few in Texas!!!
Another great website for designer digs on clearance is The Outnet! You can purchase designer clothes from past seasons for up to 70% off! The only bad thing is the sizes and quantities are limited, but if you check regularly you can always find something good!
