I never imagined I would purchase suit online, but with exorbitant prices in the stores and unavailability problems, I decided to go to Amazon. This is a high-quality suit, looks and feels premium and is perfectly suited to my physique. I am 75 lbs, 5 10 and the 40S size suits me perfect. For the price I paid for this , I couldn't expect more. Good job Kenneth Cole and Amazon.

I usually wear a 10, and this 10 is a perfect fit. Nice soft fabric with enough stretch to fit very nicely.

4/8/16  I don't know  why the bad reviews  I am 5/10 160 lb 32 waist. I ordered a size  L US it's perfect not tight it's made very well I ware plenty of formal ware  as a professional Bartender  the fabric  is just fine as well as the buttons and chain  .it's a 40$ vest  I own some that are 80 to 100 .and this is fine .it's will have it dry cleaned are light wash cycle  and low dry take out dam and press it  ... the other bad reviews are due to lack of knowledge about size . In noway does the vest appear cheap  I would not Ware it Behind the bar .also with a pair  of jeans and some nice dress shoes  everybody notices and ask where I got .. like I said it's not tight it fits and I can move in it freely ..remember it a just from the back it you want to cinch it just a little. And quite simple to take in the sides .. signature cocktails  MOBILE Alabama. .. enjoy

I am 160 and 57. I got a xxl and normally Im a large. I got a top just like this and paid $30. I like this one better. It sits nice on the shoulders and I like the sleeves. Its thick enough to smooth things out:)

Small fits perfectly. I'm 5' #145. The length is perfect on me.

Exactly what I was looking for at a price I was willing to pay.

I don't wear a 40C normally, but it fits like a 38.  IT is so adorable and it fits perfectly.  I will definitely be purchasing more.  They also had nice packaging and an envelope that could be converted for a return if need be without any hassle.

Before I get slammed, yes, I agreed to pay the 50.00, so I will suck that up. All in all, I am impressed with 5.11. The fabric is durable, breathable, and has yet to let me down. Prices are a bit out there for most, if not all, of their items, but demand is there so why not make a buck.

For the price you really can't beat this deal. I normally wear a 12/14 and the large was a tad bit small, especially around the back and chest. This will work though because I bought this for the summer & normally wear a nightgown under my robes with a few of the lower buttons unbuttoned. I think a 1x would have been perfect.

The material is thin but will work worn over a nightgown, the way I like to wear it.

I might buy again. We'll see.

I'm 5'3, 105 lbs and medium fits me just like the model, I usually wear size 2/small. The length is perfect in the front and it covers well your behind. It is a bit snug on the chest part (I'm 32b), loose down to waist part (waist 24), BUT the sleeves are just right considering I have tiny arms. So if you have bigger arms or even normal ones, I think you will have to go 2 sizes up, because material on the sleeves is not stretchable.
The cloth is great for the price, it doesn't look cheap at all. BUT it came with a horrible gasoline/factory smell. It went off after two washes.
It arrived in just 10 days, which was very prompt compared to the 1 month scheduled.
I give it 5 stars because the fit is perfect for me, and it is definitely worth the amount I paid for it.

It is a little small for size 40. In the career I have we will see how long it last, I have been through 4 belts in a year.

This is a great bargain.  Very well worth the price and it fit me perfectly maybe because I am average build, slim and tall.

okay, as many have mentioned, the sizing is NOT US sizes, I wear a 14, so based on the previous reviews, I ordered the largest size XXL, the bottoms fit great, the top is a bit roomy for me, the fringes are not as long as shown in the pic; but not bad, and for the price, you cant beat it. its pretty much as everyone has mentioned, the straps are not thick, but for me, it works. I got the neon green, I'm satisfied. Came pretty quick from China, about 9 days.

i'm 5'5 and 175 lbs, med build, my waist bout 31 and chest is 40 for dress suit, this fit just fine a bit lose, i had bout 5 inches from my crotch, but i like it lose rather than all tight up, im sure this fit 5'11 easily , but since the crotch part should be consider  if you don't like it too tight , so i would recommend this for a person 5'8 to 5'9 and leave some space at the crotch,  the 5 inches space only an estimate so it not accurate,
good build, seem to be really warm, i can use this to go ice fish and snowboard too :)  so far i'm really happy, because i bought from warehouse it said used like new , but seem to have the original tag on, no wear and tear, no smell so i think it was returned from another customer , snatched it for $35, it def worth it.
