Umgee Mauve Embroidered Boho Shift Dress

So hippy and pretty, this Umgee shift dress is embroidered front back and sleeves, the 3/4 sleeves have a slit, there are tassels that can be tied or left open, 60/40 cotton poly blend. Measurements are 21" armpit to armpit and 33" from shoulder to bottom hem. Size tag reads small, I think it's better to go by measurements and would consider more of a medium.
