I buy most of my clothes and accessories at thrift or consignment shops, or on eBay.
Most recently, I bought a blazer at Value Village for $10. The chair of the board of the nonprofit I work for complimented me on it and was surprised to hear I'd bought it at a thrift shop!
I've paid anywhere between $10 and $40 for cashmere sweaters... never any more than that.
I scored a Michael Kors handbag in an eBay auction for $50 last December--and gave it to my mom, who'd been wanting one, for Christmas.
I've bought a couple of Coach bags--one for $10, one for $13.50. One was at a yard sale, the other was at a thrift shop (marked down from $27).
I found a silk Miss Dior vintage scarf from the 1970's at Value Village for $3.
My all-time best score, though, was a Roberto Cavalli evening dress for $125 (50% off the price on the tag). The consignment-shop owner told me to add a zero to the end of the sale price if I wanted to know how much it would have cost brand-new
