I do shop at a place that sells clothing and fabric by the lb here in New York. They get literally tons of clothing from resale venues, closed stores and donations.
It smells like an attic and you have to get their early because they get crowded. I started giving tours there and helping people shop. Their are only bins to look through and no mirrors.
Everything is search and seizure then you weight and pay.
Ive found betsey johnson there, gap, ann taylor, dkny, style and co. ... and more. Vintage things too. The only thing is everything is mixed so it takes up alot of time to look through.
I will post pictures of what ive found
