I’m 5’6” and 145 lbs, with an hourglass shape. bought M in the burgundy color. I’d read about this dress running a little small so I was a bit concerned. The dress, to my joy, was a perfect fit! The dress is the epitome of understated elegance that can be dressed up or down and fit a variety of occasions! I wore it with dressy jewelry, a half-up, half-down hairstyle and gold high-healed sandals to the opening night of a play and felt so pretty. I wore it the next weekend for brunch, pairing it with a jeans jacket, loose hair and comfy 2-inch sandals and I felt just as pretty as I did at the plat. I plan to get this dress in at least one other color.
