I was wandering along the high street and saw a girl (well she was about 20) in black leggings (that really looked like black tights), black (short) t-shirt and black ugg boots. I did a double-take as I thought her skirt had got hitched up somehow. She had a black lacey thong and you could clearly see the labels for the leggings and her knickers through the clothing.
Then I saw a girl wearing footless tights and a short balerina-type skirt. All very see-through.
Am I getting old? I don't want to see your knickers!
