Runs very small. I plan to get some elastic from the craft store to make the wings bigger so my dogs can still wear them for Halloween. I have two bichons, 10 and 13 lbs., and the elastic fits around their legs, but it is extremely tight, and I would worry about it cutting off their circulation (not to mention it is not comfortable for them). So, unless your dogs are teeny tiny, you will probably need to make some modifications to this item if you order it.

I ordered the red one in size xl and it's way to small my yellow lab lbs is 75 but he is a 2xl

Ordered an xl for my 67lb boxer/lab mix and it very tight on him. I would recommend going a size up, aside from this, it is a great looking harness

Yes, to all the other reviews that this thing runs SMALL!  Although I paid attention and ordered a LARGE for a dog that weighs less than 17 pounds (corgi/wiener mix)--and it fits, very snug! But it works and he likes it.  Also, the purple is not purple, its PINK.  So much for my little male dog holding onto his male vibe while I wait for the blue one to come in!  It was so cheap that it wasn't worth returning, and it's chilly so my little male will have to cope with pink for a day or two :)

I bought this for just one lab, and thank heavens it's as cheap as it is because I can hardly do anything while I'm in it!

I bought a small because I usually run small/medium and I figured this would be baggy enough anyways but while the torso fits perfectly, the arm holes are sewn with a smaller seam around my bicep so I can hardly lift my arms out and if I flex just right, I could probably she-Hulk right through it!

I'd definitely order a size up!

Pros: Very long torso, would definitely cover you up  Cons: Arm holes are too small!
  Thick fabric to protect you
  Fits true on the torso

Runs  small I always buy a Large for my dog so I got this in a size XL so it could be big and its very small on my dog.

Runs on the small size, I wear an X-L normally and this is a little snug and uncomfortable, hopefully they will stretch

It's a beautiful looking product but it runs super extra small.  Example: an XL is like a S/M, which unfortunately does not work for my English Bulldog.

Im so disappointed with how small this is. I read the reviews and ordered up just in case. My dogs are only 16/17 lbs each and neither can where it. They normally where a medium from the store so I got a large. I would need an xxl in order for them to wear. The large is made for like a 10lb small dog. It is very well made in my opinion though. The picture of my dog is with the buttons not done. Its tight across the back.

Cute top but very small! I wear a L/XL in junior and this was closer to a S/M, I ordered the XL

Bought a size XXL for my mom and it was way too small.  This hoodie runs quite small.  I wear a L/XL myself and this hoodie fit perfect on me.  The material is soft and good quality, just runs real small!

Surprised at how small this fits as an XL shirt.

I have a 80lb black lab, per the sizing chart he would wear a XL. Wrong! Way to loose, now I have to go through the process of returning! In addition to that, the Velcro seems flimsy. Doesnt want to stay fastened. Going to a local pet store to purchase with my dog to make sure it is sized properly now!

Bought an XXL but I  wear a med/lg & was glad I did . Runs Very small and other reviews helped me decide. I added lace to make it look more festive for a German themed birthday.

Love Chilly Dog Sweaters for my Lab/Pointer Mix.  This particular Chilly Dog sweater seems to run a bit small due to the shawl collar.  I would suggest ordering up one size on this style.  Had to return this one as the size XL that my dog usually wears in Chilly Dog sweaters was way too snug for him in the chest area.  Well made though as all of the Chilly Dog sweaters are!

It's very pretty, especially for the price, but it runs very small. I had to send the L back and order an XL. Hopefully it fits!
