Bought a black pair in size 4XL quite a few months ago and once I tried it on, I knew I needed more! I ended up buying one more black pair and one nude. They're buttery soft and fit me absolutely perfectly! I have quite a saggy tummy and this thong is nice and highwaisted, so I don't have to worry about re-adjusting. They are slightly higher in the back which can be a nuisance but most of my pants are high-waisted, so they don't ride up past the waistline. But some aren't and I can't wear them with those as they stick up. Perhaps I could've gone for a 3XL but my size is 4XL for everything and I wouldn't want to chance them being tight around my inner thighs, so I suggest sticking to your usual size unless you're absolutely sure a size down will work with your measurements.
