I don’t like VPLs.
I don’t get it.
When you wear tight almost see througgh-ish beige trousers, you need to be very careful with what you’re wearing underneath, i.e. panties. Today there are two girls who wear beige trousers with a cristal clear VPL (=Visual Panty Line) on within my sight. That’s a fashion terror I must say.
For all occasions, the safe choice of underwear is a plain skin coloured no VPL one. Don’t wear white panties when your put on white trousers. That makes your bum area even whiter and look even more obvious.
