Nice leggings......but
Special Size: 19" Capri without Pockets, Size: Small, Color: Taupe
So, I bought two pairs on sale....one in navy and the other in taupe. Both pairs have a streak mark on the same side, same exact area. I'm on the fence about returning them but I did get them on sale and if the mark doesn't come out in the wash, I can't really wear the in public unless I wear something long to cover the upper thigh area. They fit great and are very comfortable but then there is that unsightly mark. For reference, I am just under 5'0, 105 lbs and bought size small. I will have a think about it the next few days about returning them...or not.

Honest Review- Recommend
Color: Black, Size: 4-5T
Material is of good quality, it is flowy enough that she doesn’t sweat or get too hot. The length is a tad longer which I don’t mind for my 4 yr old of average height. She thinks it is comfy and loves wearing it to the golf course to match mom or to the park or pickleball courts. No built in shorts on this dress, which is okay considering how often we use the restroom.
