We are all wearing this set in XS. The XS felt snug initially but it stretches out as soon as you move so it got more comfortable! We all 3 wore these all over NYC - day after day!! I love the cardigan alone but I think I would do a small in it if I wore it alone so that it accentuated the fit / cut. Madi & jenna are both petite build - smaller ribs / chest / hips and I love how the cardigan fit them — a little more baggy but fitted through waist! Revolve x Emily Gemma
