No.
My best find was 3 bags of new clothes left near a rubbish bin at a shopping center.
A nearby boutique had closed for business.
At the time it increased my wardrobe twice over.
Suits, dresses, slacks, tops and yes.... Lingerie.
All popular sizes.
Most fitted but some fashions were very way off.
It took me weeks to try it all on and here I am in the middle of the night with what could have been construed as stolen clothing.
To answer your question,there is a surprising amount of clothing left in the street.
My wife would not let me pick up the wedding dress I saw on Waikiki Beach.
Lots of people around at night and it is warm and balmy..
