These are currently my favourite tights, but it is too cold to wear them nowadays, so I layered them over some charcoal gray tights. I think they are Chinese Laundry.
I have way too many pairs of nylons, stockings and tights. Since I've been 11 or so I've been buying vintage stockings at thrift stores. I think I have over 300 pairs by now. Here are 2 storage tubs of stockings. Although they seem overwhelming in number, I'm glad I bought them, you rarely see them anymore. Not pictured are the cabinets, drawers and boxes of modern tights.
Closeup of some nice ones. Some I collected because of their graphics, others because they were oddities. Check out the crotchless, buckle at the waist ones on the right.
