Avery X. ★★★★★

The modal fabric is unbelievably soft and doesn't dig in at all, even after a full day of wear. I've washed these a few times now and they've kept their shape with no pilling. The chestnut shade is a nice change from my usual black and nude pairs.

Michael L. ★★★★★

The modal fabric is unbelievably soft and the chestnut color is a gorgeous warm brown that doesn't show under light leggings. The waistband sits flat without digging in, even after a full day of wear.

Emma J. ★★★★★

I've washed these about six times now and the chestnut color hasn't faded at all, which honestly surprised me for modal. The waistband sits flat under leggings without digging in, so I've basically been living in them on weekends. Ordering two more pairs.
