I discovered them a few years ago at Macy's, but now I order them online from Amazon in packs of three. They have moderate coverage in the back but stay completely undetectable under leggings — no visible panty lines here! —Cai Cramer, Shopping Writer Aerie Ribbed Cotton Boy Brief Underwear PHOTO: Aerie $9 at Ae.com This underwear is by far the comfiest that I own — I've bought about six or seven pairs. These are seamless enough not to show through most clothing but still have plenty of space and stretch. They're quite thin and breathable and have held up well despite many laundry cycles. — Madison Yauger, Shopping Editor The Best Period Underwear of 2024, Tested by PEOPLE SPANX Thong PHOTO: SPANX $50 at Spanx $50 at Shopbop.com We’re big fans of Spanx here at PEOPLE. I’d been searching for a seamless pair of underwear that didn’t roll up under my leggings while working out and could go undetected under something as thin as a slip dress, and these hit every mark. Though they only come in two sizes (one size and one size plus), the material can stretch up to four times its original size. — Alyssa Brascia, Shopping Writer Fruit of the Loom Micro-Mesh Bikini Underwear PHOTO: Target $17 at Target I've bought at least two packs of these comfy panties in the past eight years (only two because they’ve held up). I love them because they're made from this spandex-like, breathable mesh material but they have cotton in the center, where I need it, which makes them so cozy. — Shalwah Evans, Senior Shopping Editor Aerie No Show Thong Underwear PHOTO: AE $9 $6 at Ae.com I swear by Aerie underwear and have been wearing them for at least 12 years. As someone who wears leggings daily and doesn’t like a panty line, the Smoothez No-Shows are my go-to. They’re smooth and soft and have a barely-there feel. I own all 13 colors! — Kayla Kitts, Shopping Editor lululemon Bikini Underwear PHOTO: lululemon $18 at Lululemon Lululemon accidentally added a few pairs of these in a package, and they were coincidentally in my size. I have already purchased more! While I wear seamless thongs during the day, I do like wearing bikini underwear at night for bed. These don’t bunch up or slip, and they’re stretchy, breathable, and lightweight. — Kayla Kitts, Shopping Editor The 29 Best Plus-Size Underwear for Breathable, All-Day Comfort Auden Bikini Underwear PHOTO: Target $6 at Target I love Auden's Invisible Edge Underwear from Target, and I'm also a repeat buyer of the brand's stretchy cotton undies. These are my go-to's for wearing under loungewear, dresses, and wide-leg jeans. They're so comfortable and great for days when I'm not feeling super "cheeky" and just need a solid pair of underwear. — Erin Johnson, Associate Editorial Director PINK Bikini Panty PHOTO: PINK View on Victoriassecret.com I’d be lying if I said I haven’t owned these comfy hipsters since high school — but that’s just a testament to how well they hold up. They may be pilling a bit after close to 10 years of washing, but the Pink Seamless underwear has remained just as comfortable as the day I bought them. — Cai Cramer, Shopping Writer
