This amazing dress from Buykud can be worn with full length sleeves with elastic gathering at wrists or button off the sleeves for 3/4 length look. No size or fabric tag but fabric is like a cotton/linen blend. Slightly gathered and pleated at bottom, pockets on sides. Pit to pit 18”, sleeve length (long) 22”, length 45”. I am wearing in photos and I’m 5’6”. Probably size S/M.
