Obsessed with this set but it just doesn’t look great against my pale skin tone. Let it sit in my closet for 6 months convinced I was going to take it to Greece this summer but it’s not making the cut. Still NWT! Both are a AU 8 = US 4 Fits perfect on me as 5’4”, 26” waist, 34c Skirt is adjustable so sits comfortably but definitely can fit a medium. Likely too large for an XS even with the waistband tie. Amazing set for mix and matching too :) Snag this before I change my mind!!
