These are fantastic! I'm a US 12, XL in waist and low L on hips, so went with L, and they are perfect. They stay in place, they don't move around, and I can ignore them all day in the best way. I've been wearing my pairs on rotation for two weeks now with no complaints. They are about 1/2" above my belly button. and look smooth under my clothes. I tried M, and found those to be a little small on me, though L is plenty big and they are comfy and don't dig in at all. I prefer L in Axis, Frame, and Rosso, and it's the same for these. No tight waistbands, no rolling down, and no wedgies. These high waists are a win!

While I usually wear an XS in dresses, I chose the Small in the roam high waisted bikini to use as a smoothing garment under my Wool& dresses that are tighter in the waist. I do wear a small in Frankie as well. They are comfortable and fit well. I could probably have worn an XS but am happy with these. I bought according to the fit chart and it was accurate for me.

This is the most comfortable pair of undies I’ve ever worn. I don’t have any discomfort of any kind during the day or night. They fit and feel fabulous!

The leg openings are too high in front causing the underwear to ride up in back. I don't need my underwear to look cute. I'm the only one who sees them. I need them to be comfortable. Adjusting them all day is not cute. Also, they sit about 3 inches below my navel which I wouldn't call high waisted. I'm 6', 167#, 43" hips, ordered a large. Nice material. Only wore them once so I can't comment on how long they last.

These are a perfect brief underwear, grannies panties!
They don't stretch out at all with daily wear & handwash at night and dry by morning, ready to wear. I bought 5 pairs & tried x-large but they were a bit too large & bagged in the rear. I am not exceptionally large in the bottom so if you have more bubble maybe go for your normal size. I sized down by 1 and large is perfect for me. My trial with hand wash and dry was good for 4 days & after that time I felt a normal wash & dryer would be good. I want them for travel packing and I think they will be great. I bought black and am super satisfied. Will see how they hold up to daily use. No rolling down, no riding up & not tight at all. I highly recommend. I am about size 16
