This Thursday, Housing Works will sell 500 pieces of vintage Yves Saint Laurent clothing, the result of a generous single-donor contribution by London-based New Yorker and English professor named Annie Janowitz. The clothes had belonged to her late mother, Adeline Tintner, and after Janowitz's father passed away earlier this year, Janowitz finally felt that it would be the best time to donate the collection to charity. And what a collection! Evening dresses are $200, leather skirts are $90, a blouse is $50, jackets are $125, and a double-breasted pin-striped suit is $150, available in sizes 32 to 44 (which is equal to 2 to 8). Plus, all profits will be donated to homeless and low-income New Yorkers living with HIV/AIDS, as with all Housing Works sales. We took a little trip to the Housing Works warehouse to check out the potential picks — and there are plenty. To get a glimpse into the sale, click ahead for the slideshow.

Housing Works Thrift Shop, at 157 E. 23rd St., nr. Lexington Ave. (212-529-5955); Thurs., Dec. 11 (6–9).
