The fit of these is like an XL. The material is Lace see thru backing with a dark metallic pink front and crotch with black cotton crotch liner. These come with 24 hr. wear prior to shipping with proof of wear photo's. Add-on's are available and shipping in the US is free. I am a stay at home care giver and will wear the panty's doing all kinds of chores and work. I will wear them out, during sex, masturbating, and of course while working on my site's to bring you the most wonderful strong but sensual scent of a woman that wants to fulfill your dreams and desires.
