PORTLAND, Ore. (AP) — If you purchased caffeine-infused underwear because of promises it will make you thinner, federal regulators say you were hoodwinked — but at least you can get your money back.

The Federal Trade Commission announced Monday that two companies — Norm Thompson Outfitters of Oregon and Wacoal America Inc. of New Jersey — have agreed to refund $1.5 million to consumers who purchased “shapewear” that supposedly can reduce cellulite and fat because it is infused with caffeine, vitamin E and other things.
