Perfect fit! Bought as part of a set for a bachelorette trip and they are so comfy. Look exactly like the listing photos. Wore them through a Pilates class and a day of errands with no issues. Love the baby blue color with white contrast binding. Perfect stretch, fabric squat proof (thick enough nothing shows when you bend) and very durable.

Soft, fit, and love the color

Size: XX-Large, Color: Slate Grey/White

I love how soft these are and the grayish-violet color. They seem well made and wash well- especially for the price. You can’t see through them. They are mid weight so they keep you warm enough for air conditioning and Florida cold. Probably not snow worthy or wind strength though. They are true to size if you want them to fit but not cling or act like leggings. They have just enough room. I bought the matching jacket but I’m more thrilled with just the pants. The jacket fits as it should but not over my too many milkshakes stomach.
