I love this skirt and being able to match! I tried both this one in size 14 (fits like anXS) and the women’s S. The women’s one felt slightly bulkier to me (maybe more fabric around?) and a little longer. Personally I liked the fit of this one better since I wanted it higher on my waist, not lower waist and floor length, so I kept the 14. It was maybe a little tighter than R+Cs normal XS so if between sizes I’d do a 16 or order women’s sizing if the item is available in both. Overall I love the fabric and fit though, especially the high slit! For reference I’m 5’6” and 120lbs, it hit a little longer than mid shin.
