Panty Drop

What's in the box: The mystery option is a three-pack of Perfect Panty underwear in surprise colors, and regular five packs let you stock up on one style.

Panty Drop is a US underwear brand built around fit for plus-size bodies, with every collection offered in sizes up to 8X. The company says it adjusts each size individually instead of simply scaling up a small. Its designs use wider gussets to prevent "lip slip" and higher waists for full tummy coverage, which helps reduce chafing between belly and thighs. Styles include briefs, boyshorts, a cheeky boyshort, thongs, shorts and the Perfect Panty line. That line includes a mesh option with a cotton-lined front panel, and several other styles are 95% cotton. Single pairs have a regular price of $18 to $20, with sale prices from $12.80, and five packs are available. The closest thing to a box is the Perfect Panty Mystery Color 3 Pack, which sends three pairs in surprise colors. It was sold out when we checked. The site does not describe a recurring subscription plan, a delivery schedule, or how to pause or cancel. Think of it as a shop with bundle deals rather than a monthly box. New customers can get 20% off a first order by signing up for emails. If you have trouble finding underwear that fits above standard plus sizes, Panty Drop is worth a look. If you want automatic deliveries, expect to reorder yourself.
