Okay... I have exchanged this product and am waiting for the larger size to come in so I may have to update this review in the coming week.  Also, the company was great about responding to my request to exchange/return so we'll see how this all shakes out in the end.

That being said, I'm 5'3" and would normally fit squarely into the "medium" size on their chart.  And I do, sort of.  The girth was not a problem but the length of the torso, arms and legs are all incredibly short.  Be aware of this!  The length of the arms for the medium fell mid-forearm for me--a good five inches above my wrist!  And I don't even have monkey arms! I mean, for my costume, I'll be wearing elbow length gloves so it wouldn't be such a big deal but the length of the torso itself is super-short.  The medium fits a 5'3" at the tallest and even then it feels about an inch or two uncomfortably short.  I'm exchanging because even though it did mostly fit, it didn't have enough wiggle room vertically to make me believe I could rock out a comic conference without quickly displaying the old toe of camel.  Also, weirdly enough, the boob darts were quite high to the armpit but since it's all stretchy it didn't seem to be a big deal.  The legs were a little longer proportionately than the arms but still ended several inches above my ankle.  Again, I'll be in boots so not a huge deal but this was not made for long people.  Heck, I'm not sure it was made for not-long people.

The baseball style shoulders and high neck make for a neat cut.  It feels sporty and superhero-ey even if I will be ripping out the whole center front zipper and back for Molotov Cocktease.  The zipper is plastic and goes down to about the navel and is solid black--a nice touch.  The shiny fabric has enough 'wet look' to be a good comic personality and the girth is probably stretchy enough to accommodate another inch or two on the 'Medium' measurements.  I'm quite ample in the butt and hips and was surprised it fit so well on the ol' curves.  It seem to be made well enough for a few runs as a costume but I wouldn't make it a part of your regular circulating fashion because I'm not sure how long it would hold up.

Overall,  I like the look, the quality, and mostly the size given the price.  The company responded quickly to my request to exchange so we'll see how the 'large' size compares.  Even if it's a little loose in a few places, it might be necessary to get the length I need.

My advice:  Don't order unless you're 5'3" or shorter, otherwise you're probably okay.

***Large size arrived and definitely fits torso length better.  Of course, it's also a little big girth-wise but I'll be cutting it down anyhow.  Customer service was prompt and courteous for the exchange.
