Aerie Black Friday Cotton Underwear Sale

We start with fabric content, waistband construction, and seam placement. Then compare leg openings and back coverage to find styles that work with your everyday outfits.

Cotton is a natural fiber, while cotton blends combine cotton with other fibers, such as elastane for stretch. Check the fabric percentages in each item’s description rather than assuming all cotton underwear is made from 100% cotton.

Briefs generally offer fuller back coverage, bikinis typically have narrower sides with moderate back coverage, and thongs have minimal back coverage. Details can differ by design, so compare product photos and descriptions.

Start with the care label, since washing instructions can differ for cotton blends, lace details, and elastic trims. Separate light and dark colors, and follow the recommended washing and drying settings.

We love pairing similar colors for a matching look or mixing printed underwear with a solid bra. A shared detail, like ribbed texture or a lace accent, can also bring the two together.
