I am a Reg Large.  The torso is a little small on the swimsuit.  I could have used an XL, if they carried XL.

I'm 5'8", 185lb, athletic build, wear a 16" neck and 33" sleeve. I think 40 or 42 inch chest, but I can't find the number on my suits and I don't feel like remeasuring. The Large is absolutely huge. Only large t-shirt that I've been too small for in memory. Returned it and got a medium, which fits fine, but the neck is oddly loose. Quality, price, and comfort are adequate.

It's a long shirt, but this is a deliberate design to prevent untucking.

Not good for people with longer torsos. I am buying a second in 3XL and will try that. Excellent otherwise.

I'm 120 pounds, pretty curvy for my size. I bought the medium and this made me look like a balloon.

My husband is a normal size large, 5'8, 180lbs, 36 inch waist.  This fit well with some give and take.  The red tunic was long so it would be good for taller people.  The coat was large and long with long sleeves, so it would be good for taller people or heavier people.  The limiting factor is the red tunic under the coat.  If you have a gut, it will show, there is not a lot of extra room in the tunic.  It is stretchy fabric but it will cling to your stomach.  My husband is in his 60s and has a slight stomach and it did not stretch around  and show it.  It fit him exactly like the guy in the advertising photo.  I'm talking about a full blown beer gut, this will cling to that kind of stomach.  It is a great costume. It's a little chintzy, don't expect great fabrics, but it looks good and it will do the job nicely.  I wish they made Ladies costumes with a swingy coat because is it super comfortable.

I'm 6'4" and it's 80% torso. It's hard as hell to find tall tshirts. I used this one for yoga so my belly don't fly out doing my got dang sun salutations and gross everybody out at the studio. They're already horrified at the giant with the beer gut and pasty skin trying to contort himself like a normie. Enough is enough, you know. This gets the job done.

The sizing is correct. I wear a size 16 and I ordered a 16 and it does fit but the torso I feel like is really long. I am 5'1" and carry most of my weight in my stomach and butt so it kind of looks like someone put a bathing suit on a potato. Not the company's fault obviously, just pointing out that if you're short and your weight is in those areas you might not like how this fits. Otherwise it's a great bathing suit. Seems well made, nicely padded in the breast area, generous amount of room for the ladies without being too big. The fabric appears to be a good quality. I received the item quickly and it was well packaged. I'll wear it with a cover up probably when I take the kids to the lake.

I had to return this item as it was too long for my torso. I am 5'3" and 130lb Very good quality and customer help was quick and easy to work with!

According to the description, medium should fit folks 161-170cm tall. I'm 5'4" (162cm) and this (medium) barely fit. When standing straight, I could feel the onesie pull up around my calves. If I wore dino feet and stood like the model, there would be bare skin showing. It didn't look like the photo where the legs comfortably end at model's ankles.

I had replaced this with a large and that fits a lot better. It still pulls a bit around the ankles but at least it reaches my ankles. Large wasn't noticeably wider than medium.

Quality-wise, it's ok. There were quite a few loose threads to snip but it's warm and fuzzy. Width-wise, it's fairly loose and comfortable. The hood is large enough that snout of the dragon can cover my eyes if I wanted. Quality between costumes may range. For example, the large had dark green buttons and fewer loose threads while the medium had light green buttons and lots of loose threads.

One thing I didn't expect was a zipper across the butt area. If you look at the model's back side, you can see a ridge just under the dino's tail. This is a zipper that goes across the entire back side. I'm not sure why it's there but I can definitely feel it when walking around or sitting.

Overall, the sizing is a bit small but the costume itself is comfortable.

Based on reviews I made sure to be realistic with my size. I tend to vary between small and medium, but this vest is definitely form fitting to my chest and stomach, so I chose medium. I am happy with the fit on my body. The neck strap isn't adjustable and I found it to be a little loose, but nothing too serious, it just warrants me to pull the vest down a bit more on my body. I intend to were to festivals and in warmer weather, however, this is completely appropriate with a tank or short sleeved shirt. I like it, and the material seems durable enough, though I have yet to wash it.

I'm 5'10, usually wear a US Medium (size 8/10), and I have a long torso with a 36C.  I followed the bulleted sizes provided - due to my measurements, I went for a Large.  Once, I tied the halter parts of my swimsuit up, I was hunched down -- not a good look for me or anyone really for that matter.  I totally resembled It's Pat from SNL.  The suit would totally be cute for someone who doesn't have a long torso.

I have a long torso and am plus size and the strap is still long enough to wear this cross body! It is smaller than I would have liked, though

I really like it and it is made for a long torso which I have. I've only had it for a couple weeks but I feel it is working!

Nice fabric. Long, which was what I was looking for, since I have a long torso. It's just way too big, but I also recently lost weight. It still seems big for a Medium.

I am a size 10-12 above my waist and more of a 12-14 below.  I ordered a large.  The bag they sent had a bar-coded sticker that said large but the costume inside was marked medium on three pieces.  Well, the shoulders and bust fit nicely ( I have a c-cup) but from the waist down the coat would not come together to Velcro.  I didn't have enough time to exchange before Halloween, so I decided to add buttons to the top and wear it open from the waist down with a black skirt underneath.  Overall, I like the costume and I think that the large would have been too big through the shoulders.  I hope this helps someone trying to figure out what size to buy.

I'm 5'10" and 185 lbs. I ordered an XL and was swimming in it.  I think that even with a larger bust I could possibly fit in a Medium comfortably (perhaps).  It's also a tad cheaper looking in person than in the picture.
