What will they think of next? Japanese company Ligre has taken it to the next level with a line of panties that are designed to go over top of your pillow.

They look like a generic pair of panties but they're 22-inches by 32-inches and fit most standard pillows. It gets stranger... The pillowcase collects oils and sweat from the users head as they sleep.

That collection will eventually buildup and cause the crotch of the panties to discolor, presumably attracting a certain type of customer.

The panties start at $20 a pair and Christmas is coming up. This might be the perfect gift for your weird uncle.

You can buy them at Village/Vanguard.
