Size L, like new condition. Inside tag was removed to wear both sides, but proof of purchase/sizing is in photos. Which side is the inside and which side is the outside?! I DON'T EVEN KNOW, I'M FREAKING OUT HERE! This crazy little number can be worn Mucha-side-up or La Trappistine-side-up, whichever floats your boat at any particular moment. Change your mind about your outfit halfway through the day? Feel the spontaneous need for something different? Not a problem with this dress! ** This is a limited product – it's gone forever!! Composition: 82% Polyester, 18% Elastane
