The sizing is off a bit.  We had to exchange this ring twice from a 13 to a 12.5 to a 12.

I really like these harnesses but the sizing is odd. Smalls are too small for my dog, and they chafe his armpit region, but the mediums have stretched like crazy. I still think he's secure in the stretched ones but we have to velcro it past the actual velcro attachment and to the harness itself. It wasn't nearly that bad when we first bought one.

It worked for what we needed. Though it is a bit snug for the size. Buy a bigger size.

i love it, but the size is a bit off. I bought a large and it fits a bit small. I usually wear medium or large.

We may have to exchange it for a larger size after our daughter gets it for Christmas.  Not sure it is going to fit.  It looks small and short.

The general size it fine, but the fit is very around the controls and gaps elsewhere. We had to just trow it away.

It's a great little costume, but it won't last forever.  It's the usual packaged costume quality, but it made my little boy ecstatic when I surprised him with it for Halloween.  The sizing is really off, though.  My son is just over 5yo, 46 inches tall (so yes, tall for his age) and the size 6 was a pretty tight fit.  That said, the size 8 would have looked very messy.  It's a few inches too short in the sleeves & pant legs, and there isn't much room for his torso to grow, but it is stretchy, so he wasn't uncomfortable.  The mask seems to be an adult fit, but we only put it on for photos, so that wasn't a big deal.  The tail is attached with weak Velcro, so I threw a few stitches in it to keep it attached.

Too small and we sent it back. The description was way off and needs to be adjusted.

The sizing isn't quite right. It's a very nice product, but the sizing is off a bit. It was too tight in the upper part of the body.

I ordered a size up and we still had fitting challenges.

The pants were very big and baggy -- my son wanted a more fitted look, so grandma too the pants in. Problem solved.

The jacket looked boxy and bulky, until my son stretched out his arms -- then it was too small/tight.

Overall it was an OK buy -- renting a tux would have cost about as much -- hoping we can get through one more prom with this one.

Not quite the fit but we were able to modify quickly.

The cover didn't exactly fit the key to size, but we made it work as best we could.

Cute jacket, but the sizing is tricky. Since it jumps from 4T to 6, it's tough, because the size my son probably needs is right in between. He is at the top end of most 4T size ranges, so I figured he'd just have some room to grow in the 6T, however the sleeves were several inches too long, and the jacket came halfway down his thigh. It is cute in person, however I obviously can't speak for durability. We found a brown leather jacket at Target that fits him better, so we'll be sending this one back, but if your kiddo isn't between sizes like mine, this is good deal for a decent looking jacket. Just a heads up on some things that might help you make a decision: The faux leather is quite shiny in person, and the back of the jacket seemed a little shorter than the front. Also, the zipper stuck in several spots and appeared to have been sewn in with one side slightly longer than the other, so there may be quality issues. It is a cute jacket though.

It didn't quite fit what we bought it for and had to be altered.  So it doesn't exactly meet its description, however, the price was right and we had the skillset to tweak it.

The costume is very cute but the sizing is a little bit off.  It fit my dog (20 pound beagle mix) length-wise but the width was much too short, especially for a medium.  I had to add more elastic so it would fit around his waist.

The sizing was a little smaller than normal. Had to purchase a size larger and return the original product back.
