NWOT, Lyra Organic Cotton Tiered Maxi Dress in Blue, size XS

Such a beautiful dress! Saw my friend wearing this and ordered right away, but it’s sadly too big on me. Brand label is “Modern Citizen” This item is brand new, without tags. I don’t know where the tag is; perhaps it came in a plastic bag sans tag, unsure. Either way it’s unworn b/c very unfortunately it’s too big for me. I’m 5’2, 115 pounds, 34C. I normally take an XS or S in most clothing. It fits me but has loose space, so I felt I’d need an XXS if they had. I missed the return window sadly. *The last two photos show a side by side of the approximate measurements I took. One is from armpit to bottom & the last is top to bottom length. Please message me with any questions!
