It fit exactly like the 4X

Because a number of reviews stated that this product ran small, I ordered a 3X (What I actually wear) and a 4X (A size larger) to make sure that I had one the correct size to wear on vacation.  My order was shipped in two packages.  The 4X arrived first, I tried it on - fit a bit more snug than a normal 3X fits me.  When the 3X arrived I was going to return it, but my wife told me to just try it on.  It fit exactly like the 4X.  I laid the two shirts on top of one another, and although one is marked 3X and the other marked 4X, they are the exact same size - same length, same width, etc.  So I'm not sure if the 3X runs a little small or if the 4X runs a lot small.

The shirt is a smaller shirt for a 4X. It is a small fitting shirt with not much shoulder room.

This is my second tee in this style the first one I ordered was a 4xt and I like the fit of it but it's a little longer than even I like.  So decided to just go with a 4xl this time and it fit perfect the width of the shirt isn't ridiculously wide so it doesn't look like I'm wearing a wing suit.  I have a longer torso so if you usually need tall tees you will be fine just getting a regular length one in this style. I'm 6'2" mostly torso height as my legs are short.

This was the only Nursing tank I found to fit me for a reasonable price. I also liked the nursing bra version.... it was exactly like this bra. I was a 38DDD prior to pregnancy and while nursing I was closer to a 40G(ish). That size is so hard to find. The fit of the 3X worked great.

I wear a 3x normally, I followed suit and got the 5x. It fits perfectly. Very nice dress, I got a ton of compliments on it and I feel pretty in it. Came back to order one for my daughter but they're all sold out in a Large.

I got a 4X but it fits like a 3X. I wish it came in 100% cotton. But it's obviously a fantastic design. I highly recommend you get one one size larger than your normal size.

I originally ordered a XXL, but, I gave it to my 25 year old, 100lb cousin. I reordered in a XXXXL, yes 4X, and it fits perfectly. I'm a US M/L, 5 2, 150lbs.

Fits well. My husband wears 2X, and it is a 4X but good quality.

After washing the XS/4 (on cold, low dry) it is the same size as a 2T shirt that was in the same load!

It's always a challange picking out something like this online, however I felt this was exactly what I expected when it was delivered. It fits appropriatly and wasn't horrible quality. The little ribbon like bow in the front was rather cheap looking but aside from that it was totally satisfactory. I ordered the med/large and felt it was a good fit. I am 5'3" 145lbs with a larger chest. I usually prefer somthing with more support but the halter top makes up for it.

I'm 6'5" and 220 lbs. I bought the size A4 and it fits perfectly. I rinsed the top with warm water, put it through a spin cycle and tumble dryed it on high heat with fabric softeners to break it in a bit before my first class with it and it still fit just as good as when I took it out of the box. Great material, well made for the price and it looks, feels and performs like it should. I put it through it's paces at the dojo and I'm very pleased with my purchase.

It fit perfectly and still looks new after the last 4weeks of wearing it.
