This costume didn't fit in any way.  I suppose if I was eight feet tall the midsection would have fit but instead it was bunched up or down past my knees.  In aiming for a 'one size fits many' it ended up so discombobulated it would fit no one.

The costume was cute and the material a decent quality.  The problem is that it was supposed to be "one size fits all".  My sister and I both normally wear a medium and could not get it on at all.  I gave it to a friend who is size small.  She could get it on, but said it was uncomfortably tight.  This item needs to be relabeled as a child-size costume.

disappointed with the other costume pieces, so I sent this back as well. It may have been okay if the rest of the costume didn't look like it was made for a large 14 year old

I honestly don't know what to say for the fit really....  I am somewhat pear shaped and usually wear a small.  Though most costumes run smallish and I tend to get mediums in anything with a separate bottom, after reading other reviews I decided to stick with a small size, not being abundantly "blessed in the chest."  I figured I had another similar skirt I could wear that was a little more conservative.

The top was too big, I'm 5'8" and I wear a B-C cup.  The bottom.... the bottom was comically too small in about a bazillion ways.  The circumference was closer to the size of a garter than a skirt (remember, I didn't expect that part to fit very well, but that... that was beyond not fitting well--I had to check the inside label to make sure they hadn't gotten the pieces mixed up), and the length--definitely not as pictured.  It was about 6" long and even worn at an extreme low hip placement it barely covered my underwear in the front and didn't in the back.  Needless to say, I wore the other skirt that came mid thigh.  The tights were fine.

The only people who could wear the cut I was sent have got to have manmade enhancements up top and typically wear a 0-1 on bottom.  Really, the top was a medium, the bottom was an XS.

not a quality costume by any stretch of the imagination. First the one size fits all isn't true of you're on the larger side, but more important the material doesn't breath so not wearable for any length of time.

The item is grate, unfortunately it didn't serve me, since I needed it for a costume and it's specs did not measure up to my needs.

Too small and material feels plastic like with no real stretch to it. It sounded a bit different from the other reviews. Not sure if this might be a different version of the same product or what. Strangedly enough the gloves were too big compared to the rest of the costume.

I ordered a medium and am 155 at 5'7" - but very slender other than my wide set hips. The pants wouldn't go over my calves which means definitely go with a size up.

I am returning it :(
I will be putting together my own costume instead.

I was pretty disappointed.

I returned this item as it didn't come anywhere near to fit, plus it was of very cheap quality and not lined.

It was WAY too big.  I read reviews that said it was too small - had to see for myself.  At least he'll have a costume for several more years.

This costume was even more see through than I thought it might be, and the fit is just tragic. There is zero give in the material, so you either fit or you don't.

The costume I got looked nothing like the picture.  The one in the picture looks to be of better quality.  My son was happy with is so, I guess we will keep it.  If it was up to me, I would return it for a refund.

The Velcro that is supposed to attach the beard to the hat wasn't even seen onto the hat. The beard is too small to go unde my child's chin even though I ordered a larger size than necessary--or so I thought. Glasses came broken. I don't recommend this costume, but at least we have a vest.

The costume looks NOTHING like it does in the picture when it is actually put on. I bought this for my 11 year old in a size large because the description said it fits most 8-10 year olds. The body suit and belt were way too big and the mask and ears were way too small. I returned this item and would not recommend it for purchase.

Bought this costume for Halloween this year. (I like to try to plan way ahead in case there are any issues)-and I'm glad I planned ahead! I am 5'4" and weigh 165 lbs. I ordered the large size, and it fit okay in the waist. Most of my weight is in the middle and I'm a bit pear shaped. So as you can imagine, this costume looked silly on me. Pretty un-flattering. I could have possibly pulled it off with a push up padded bra, and some spanks, but there were too may other issues with it. For starters, I will need to wear it to a church carnival, so I was already planning on wearing a tank top, or cami on the top, and some stretchy shorts or pants on the bottom. I did buy the boots to go with it, and also ordered the extra black petti-skirt, as these are not included. The glove-lettes, were actually comfortable, and soft, so that was a good thing. The hat was the same material and fit easily. The dress itself was way too large on top for me, and the sleeves (as others have said) were itchy, and very tight around the arm. The fitting on the choker fabric at the neck was also tight. The model in the photo must have been a size 2-6 with a double DD chest. The petti-skirt I bought did not work as it would not lay flat, so it made the dress look like a southern belle.-Not really what I was going for. Also, the length of the skirt on the dress went to just about two inches above my knees. The hat even though comfy, looked ridiculous. It's a lot taller than looks in the photo. The goggles were a joke. Cheap plastic, and very uncomfortable to wear with the hat. The stretch band on the googles was really small, so it squeezed the hat and  made it pop off my head.  I was also prepared to go ahead and order another pair of nicer looking goggles.
One of the biggest reasons I returned is that once on, you can't tell what character you are supposed to be. It's a very stylized version of Victorian steam punk. Is she a welder? Aviator? Can can girl?, Saloon girl? Inventor? There was no clear defining element to the costume that would make it obvious for anyone else to guess what you were trying to portray. There's nothing I hate more on Halloween, than an uncomfortable cheap costume, and having to explain to every single person I come across what my costume actually is. I really wanted to like it, but there were just too many things not working with it for me. I ended up returning all- and going with a leather bomber jacket, and aviator goggles and pilot scarf. Simple, easy to wear, and I can still wear my skinny jeans and boots while being modest, and comfortable around kids. And most important (EVERYONE WILL KNOW WHAT I AM PORTRAYING.)

.... seems well enough made, but was so small I can't imagine anyone over the age 6 or 7 being able to fit in it. We were going to send it back, but my daughter was in love with the costume's cap & hair, so we went elsewhere and found a dress that could be substituted for the costume itself. In the end, she looked much better than she would have in the costume that didn't fit. Also, the costume's cap & hair are certainly cute enough, but it's stitched in a way that makes it entirely too big. To hide the billowed out sides of the cap, I ended up manually taking in/sewing the oversized areas. This costume is beautiful in theory, but making it right will take a lot of time and energy better made use of by finding a different costume.

Didn't seem like an adult small. I usually wear a size 4, and this costume was way too small. Pants were not bell bottom, and were too short. Did not come with headband, as stated. Shirt was above my waistline.
