I ordered the x-small in purple. For reference, I am 5'1", 116 pounds with a small, high waist and small chest. This dress is beautifully made--fully lined and comfortable. The sequins and tiny irridescent seed beads are sewn on after the dress is assembled, and the pattern is sophisticated and not cheap-looking. The outer layer of cloth is a transparent mesh, which is not my favorite, but with the trim, it looks fine and seems reasonably sturdy. This has a side zipper, and unfortunately, it is tricky to wriggle into.
I had some fit and style issues, mainly due to being a gently-curved hobbit. This dress is cut with a very high neckline and long torso, both of which look terrible on me. I ended up wearing the dress backwards. This actually works quite well if you want a dangerously plunging neckline, like a Hollywood star. I solved the long torso and plunging neckline problem by tailoring about two inches on each side of the shoulders-- this shortened the whole torso and brought the neckline up. I also stitched about an inch up the neckline to close it up a bit more. The dress was quite flattering and much more fitted this way.
Length-wise, after my modifications and with heels, this swept the floor but was wearable without hemming.
I like the skirt on this dress -- the mermaid styling is accomplished by gores added to either side of the skirt, which is far nicer than I expected. The beads add a lot of weight and sweep to the material. I did have problems with the beads near the zipper snagging and coming loose. I ended up stitching them back down and trimming loose thread loops to tidy this up.
This dress is a good value.

The dress is so well made, made for a curvy figure , sizing is really "true to size". I got so many compliments wearing it to a Great Gatsby Party in Chicago. The option of having the v neck in front is great but to keep it modest you can wear it to show off your back. It hugs the hips and the design accentuates the curves. I loved wearing it with white pearls!

I purchased this for a Great Gatsby themed evening and I am so glad that I did. I received so many compliments from everyone there including the actors. It fit exactly as I wanted. I did not turn it backwards as I felt that wearing as it was intended was much more period specific. I can see myself wearing it for other non 20s themed events too.

The colour on this is just lovely. The fit is a little bit odd on me - too big at the top, works well across the chest (32DD) but loose around the arms. The stretch makes it super comfortable but the line down the middle stretches RIGHT in the wrong spot! I just felt like there was a sign pointing "here it is"! Very comfy and super light to wear but sadly will be returning.

STUNNING DRESS!! I tried the "V" on the front and loved the way it flattered my chest. It does have some stretch and made of great quality. I'm 5'1 and the dress hit just at my feet, I LOVE IT but will be returning due to length.
