Satiny material, pleasant on the skin, not too thin. Love this, very flattering on, but would require tape as the straps have a tendency to fall off my shoulders (but bonus as you could wear it off the shoulder if you like). A little long on me (I’m 5’5) but not too bad. The cowl neck definitely is a little low so would probably need tape there too. I find that Maija runs true to size, so take your usual size
