ICHI puff sleeve iridescent dress

This dress is GORGEOUS ! It's so hard to get a photo that does it justice. Dark blue slipdress with blue sheen shin-length button front overlay and large puff sleeves (there's an inner ruffle that keeps them nice and pouffy, see photo). I bought this dress because I loved how my tattoos would show through but in the end I only wrote it once, briefly, for that same reason. While it's tagged as EU 36, a size small would 'drown' in this dress - in my opinion, best suited for a M-L. The slipdress is very stretchy, and the dress itself is a straight cut. Both the slipdress and shell are polyester, I cannot figure out what exactly you would compare the shell feeling to, like a thicker gauze maybe. Measurements laying flat : length 44.5" armpit to armpit 21" waist 21"
