Calvin Klein Naked Thongs

I agree with the other reviewers. These are the only underwear I've ever tried that truly won't show with even the tightest dress. They are worth the money.

I love love love these thongs. I actually went and got even more. They're laser-cut so they're smooth as silk and seamless. This means that lines won't show on your clothes. They come in black, white, beige, hot pink and red. They all look pretty hot. They're super comfy and easy to wash and maintain. They also come in little ck slide tins with matching colors. I definitely think that this is a good investment.

The Naked thong by Calvin Klein is unbelievable comfortable. The sales girl at the store said they feel like you are wearing nothing at all, they don't bind or tug anywhere and definitely don't show through your clothes.
Boy, they weren't kidding! You actually forget you are wearing these things. Everything the sales people said was true, they are fantastic. Let's face it we wear thongs so we don't have panty lines but sometimes with certain fabrics the outlines can show through - not with these and the best part is they are soooo comfortable.
Well worth the $20 price tag.

The Calvin Klein Lingerie store had them in black, white, nude, red and hot pink. The website offers them in black and white.
This is how they are described on the CKU website "Ultra lightweight. Feels like nothing at all. Seamless and tagless. Imported. 78% Nylon, 22% Lycra. "
