Sifting through online customer reviews is one of our favorite ways to shop. We’ve shared the top-rated shapewear on Amazon, but today we’re adding to the list of must-have underthings by highlighting one of Amazon’s best-selling “no-show undies” (AKA undies you can wear with leggings or under a dress without the worry of a visible panty line) — and it happens to only cost $7.

If you’re as curious as we are about what people are adding to their carts, browse Amazon’s best-sellers section and you’ll come across a plethora of fashion finds.

The mega-retailer updates this section hourly, but for weeks the number one spot in the women’s underwear category belonged to Cotton for Body Lace-Trim Bikini Panties ($7). Made from the softest cotton and trimmed with delicate lace, these undies have over 130 positive reviews, making them pretty much a steal. Add these to your cart and have them in two days or less with Amazon Prime.

Comfortable, affordable, and available in five different colors, it’s no wonder why they are so covetable. The lacy cotton underwear comes in two body shapes (bikini and hipster) and has five different colorways. What’s not to love?
