Yes, Impressions has Women's Fancy Stockings which can be changed from solid stockings to fishnets and be worn underneath. I even have a mod that makes the fishnets look nicer.
And can be worn with those thigh high boots?Oh, I thought stockings, there's some tight latex pants also at Leather & Lace
Mind if you post a sshot of those "tight pants"Yes, they use the pants slot which can be worn with boots which use the shoe slot
