I recently reached out to MeUndies, and they sent me over a few pairs to sample. I tried the Modal Thong and the Lacie Thong. The website claims that the Modal fabric is 3x softer than cotton, and I'd definitely agree. I heavily preferred the Lacie to the other waistband, because I found the lace to be more formfitting and comfortable, but both styles are great. I threw them in the wash with the rest of my clothes and dried them normally, and they came out fine.
They're comfy and well made, but still quite cute. I really liked the Lacie and preferred it to similar lacy styles from Victoria's Secret or Aerie. I would love them to expand their color/pattern selections for the Lacie, and I would definitely buy more. The devil is in the details, and I loved the stitched-on tag on the Modal pairs, and though I'm sure lace is different to work with, I would love to see something similar on the Lacie.
Overall, I really love MeUndies, and I think anyone seeking well-made undies at a reasonable price should check them out. They also offer some loungewear that I'm dying to try, including hoodies, crewnecks, lounge pants, and joggers. I would love to see MeUndies expand to hyper comfy bralettes, but that's just my 2 cents. Check out MeUndies!
