I am 5'4" and 225lbs. I ordered the 4x size. This suit fit me perfectly, I'm guessing my shorter height gave me a little leeway on the weight. My torso is long for my height but I still had maybe 2 more inches in the body area for height. Enough that someone several inches taller than me could still fit but not noticeable at all as being too big. The arms came right to the middle area of my elbow but not bunched in my elbow to be uncomfortable. Same for leg length to my knees.

I wouldn't say it's 'flattering' because no clothes will make my post-baby tummy fat disappear, but it did not make me look even as big as I know I am. Glides right over my stomach without bunching up in or emphasizing every roll. Very modest, which is what I was desperately looking for in a suit. Doesn't pull up in the crotch or outline every detail of my behind. I might not even wear a swim skirt over it.

If you are remotely busty or want to avoid having your nipples show off in a cold pool, you will need a swim bra. There is absolutely no chest support in this suit at all, and no extra layer or thicker material in the chest area. This is fine for me as I'd rather get a separate suit and bra that fit instead of trying to find a single suit that fits both when the hunt for either (especially in chinese sizes) is already difficult. But it's something to be aware of.

Perfect for what I wanted it for--a little extra warmth and cover up on the body for snorkeling in Hawaii and riding a jet ski. I'm a round little Grandma - 5 ft. 2 in. and 220 lbs., and I love that this suit has long enough sleeves to cover my heavy arms and legs long enough to go to my knee. It provides easy protection from the sun and an extra layer to allow me to stay in the water longer without getting chilly. I bought the 4XL and wear my swimming suit underneath for support in the chest. It is slimming and comfortable. What a deal!

Bought if for swimming class. I usually use it 3 or less times a week. Only lasted for 2 months of use. It unraveled and became thin.
Used in indoor pool. Chlorine might not be good with this suit.

I haven't worn this swimming yet, but here is my review.

Don't be alarmed when you first take it out of the package. It looked tiny. But it is VERY stretchy! I am 5 ft 8.5", 275 lbs. I usually wear a 2x-3x (22/24) and am very big in the bust. (44F/G). I took photos of me in it for the very first time to help out other bigger folks determine what size to get!

I ordered a 4XL. It's not too tight, it feels just like wearing compression shorts and a compression top. Totally doesn't seem to restrict movement in anyway. Minimal camel toe for me, but that doesn't surprise me any. I pulled it down a bit from the stomach towards the ground and that got rid of it completely. I did the sit test and it doesnt hurt or tug or pull ANYWHERE for me. It is NOT see through indoors - probably not in the sun, either. Seems pretty thick. I am wearing a light support sports bra underneath, with no wires, just for a little something. There are no breast pads in this one (thank god, they would look weird anyway as they are always too small).

I am extremely excited to wear this on my honeymoon in florida this winter!

I ordered one of the Micosuza suits and a Bikman. The Bikman was definitely the better quality. I am 5'5" 150 lbs and a 36A. The size medium fit me snug and I liked it. The material feels strong and the seams are well done. My biggest complaint on the Micosuza was the zipper was sticky and the seam was already falling apart at the bottom. The Bikman has a strong zipper that works good and the seams were strong. The bra on the Bikman was better than the Micosuza but I still prefer to take the pads out and wear a sports bra. Overall very happy so far with the Bikman.
