This is what naughty little Brigitte does for fun.
She'll buy a cheap pair of leggings for a couple of bucks, then cut open the seam in the crotch a few inches.
When she's standing up you can just see her panties but when she opens her legs slightly much more is exposed.
She will often go out shopping like this. It's great as it just looks like the seam has accidentally come apart.
Whoops, a wardrobe malfunction.....hehehehe.
