Excellent but runs big
This is a wonderful suit for lap swimming. It offers great coverage and support, plus an attractive fit. I find the size chart to be off. I purchased a size 18, according to my measurements, but it was huge! I ended up buying a size 14. I am large busted, a DD cup, and the size 14 gave me plenty of coverage.

lovely.
this is a great bathing suit! I am 210 & 5'9" and this fits me perfectly. I love the way I look in it which is pretty amazing considering I got it to go to the pool to work out and change the way I look! I carry a lot of my excess weight in my mid section and don't feel self conscience in this (well, not in my living room anyway, we'll see when I go to the gym tomorrow). The back straps are a little tight but not anything that would prevent me from buying this suit again in the future.

I kept it and it fits, I wish the legs were a little less modest
This suit performs perfectly. It remains flat on my body except one spot: the butt. The legs are so “modestly” cut that they actually wrinkle around the bottom of the back end. The suit is extremely high quality and durable which made that one flaw worth keeping it. I did accidentally get a “tall” which I’m not, so since I wanted to go swimming and it fit okay, I’m keeping it. The suit is nice and heavy weight with a lovely dark black liner. No bust support other than a very light shelf bra so if you want anything more than that, keep looking. I do find that it’s easy to swim in, although it is hard to get off once it’s wet. I think this would be a versatile suit to use for a triathlon if you’re not looking for too much chest support. I use it strictly for lap swimming in a pool and it works great for that. I have now worn it at least a dozen times for lap swims, and it has not faded at all (I do use Suit Soak wash after I swim every time, rinsing it in the sink and let it air dry). This is not my favorite suit, as the racer back does cut in a little and make some rolls that are a little unsightly, but it performs great and is exactly as I had expected a speedo to function. Swims well and doesn’t gap anywhere even while swimming hard.

Great for water Ai Chi.
Speedo suits always fit well for this Gramma body. Well made and supportive.

Defective....straps twisted and unfixable.
Straps were twisted and sewn in that way. No way to straighten them out. Must be a reject that Speedo was trying to get rid of, hoping the consumer would not notice. Too bad because it fit pretty well except for that. Need to find a new brand of swimsuit, too many issues with Speedo lately.

Is this a SPEEDO?
This swimsuit doesn’t reflect the Speedo quality I’ve come to expect. The biggest drawback is the lack of a built-in bra or padding—it's just the fabric, which offers minimal support. It also stretched noticeably more than a typical Speedo after just one wear. The fit is true to size. Honestly, if the tag didn’t say Speedo, I would’ve assumed it was a different brand altogether—definitely not from the PowerFlex line.

Good quality, runs large
Runs a tad large but good length for my long torso. My pant size is 18 and I got an 18 tall, should have gotten a 16 though.

Bad fit, fades fast
Speedo brand is getting worse and worse. I went by measurements and it is so loose that I’m not comfortable wearing it to water aerobics again. I also have to buy a new one every three months because they start to fall apart. I’m done with Speedo.

On ne se trompe pas pour la qualité d'un maillot SPEEDO !
La grandeur était excellente et confortable ! Bon rapport qualité prix. Je le recommande.

Talle muy largo
No es el diseño más favorecedor de trajes speedo que mi esposa ha comprado, le quedo muy grande y la tela no se siente tan resistente como otros modelos diseñados para natación.
