Women's Bamboo Viscose/Cotton Capri Style Leggings

The pants are of good quality. i think I would be more comfortable in a size Medium. May i exchange my pants for the medium size?

It's breathable, feels light on the body and comfotable. However, it's a bit pricey.

I already have two pairs of these I got from Amazon a while back. They are my pjs, combined with a Latuza bamboo v neck top. On Amazon the xl black hasn't been available for a while, I was glad to find it on Etsy since the more of these I have the better given how nothing else compares. Though they were a bit cheaper on Amazon (pre tariffs, though). They are smooth, breathable, fit like they're tailored to me, allow full range of motion, and don't leave wrinkle marks in my skin. They are also fully opaque, deeply black, and sturdy and thick. I'd love it if they also came in instep length to wear on errands.
