Desigual T-Shirt Dress

Pretty Desigual 75% Viscose/25% Cotton Floral and paisley pattern One Flower is traced in jewels to give it that bit of bling Size label at the top has been removed; Label with washing instructions shows Size as EUR L but definitely does not fit L - more like M or even S My experience with Desigual is it always runs small in size See measurements in photo Gently used condition - I can't tell if there is pilling or if it is the texture of the viscose/cotton blend fibers in the fabric (see last 2 photos); full disclosure but IMO it's the fibers because it is consistent throughout the dress
