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.

Great basic!
Special Size: Long Sleeve, Size: Large, Color: Ocean Blue
I love these tops, not too cropped but perfect length. I also have sensory issues and need long sleeves when i workout and these wick away moisture + are the right thickness. Usually 19$ but i waited for them to go down 25% right before prime day (yes, that’s right before). Since its amazon basic brand, if you don’t need it right away i suggest watching price. Worth it at 19$ but why pay more.
