This is actually the second pair of these that I bought because the first pair had a tiny hole after wearing them once. I was surprised because they feel very well-made. To the company's credit, though, their customer service is amazing. They refunded me right away and I ordered another pair because these are the softest, most comfortable leggings I've ever worn. The fabric is so soft that you just want to be wrapped from head to toe in it. The fit is perfect because they don't stretch out, and they're not loose, but they're not tight in an uncomfortable way. I wouldn't really call these plus size by US standards, though. More like an XL, but will fit some plus sizes. I plan on buying several more pairs and I definitely recommend these.
Just remember that if you have a problem like some others are complaining about, please contact the seller because they'll help you very fast.
