I was a little worried because I've never purchased a swimsuit online. But, per usual the Amazon reviewers are the BEST! Based on everyone's recommendations. I was able to successfully get the right size suit! I tested my new suit out today and it's GREAT! No slip's, spills, it held on for dear life. I couldn't be happier. The sizing was perfect. If you wear a size 14 bathing suit. The size 40 will fit your curves perfectly. I will be purchasing another suit in the upcoming months. Next time in a size fit for a woman with the figure of a size 8. TYR's suits are amazing. Here's to a woman reclaiming her body after the "Big C" and massive doses of Prednisone.

My daughter loved this swimming suit she is 14 years old and we bought a women's small and it fit perfect. It washed perfectly in the washer and it's got plenty of stretch but at the same time it was tight in all the right places. The best one I've bought so far.

I love this suit! The TYR durafast suit lasts longer than any other fabric or brand suits I have tried. I am a daily lap swimmer with over 1 hour in the pool each day. I have ordered several of these suits over the years and consistently get about 11 months of use from each suit. They hold their shape well and only get a bit saggy near the 10 month mark. I hope they don't change to style or fabric!

I was a competitive swimmer and water polo player for over 9 years, so I feel like I know a good suit when I find one. This suit works great for me - I used it 4+ times a week and it hasn't loosened at all. I sized down because I prefer a tight suit, but if you don't like that I would recommend sticking with your expected size.One thing to note about this suit is it does cause sloughed dead skin to come off because it's very coarse material - which is great because the material does not loosen up! But definitely not super cute when you notice your dead skin falling like snow from the suit...Also, the straps tend to dig in if you have a large chest like I do, but that is expected.

This size guide is completely off. And now I can't exchange or return because I am 2 days past the policy, so I am out $45 with a product that can only fit a doll :(

I swim 3 times a week in a chlorine pool, and this suit holds up with no sagging for over 6 months now. I rinse it after each wear under the shower and hang dry and it is good to go. This is my 3rd TYR suit in 10 years, I swear by this brand

I was not sure which size to buy (30 or 32) because reviewers had different experiences with sizing. I measured myself carefully to the TYR size chart. I bought size 30 (I wear XXS or XS in women's swim) and it was true to size for me, perfect in hip/waist/bust. The elastic around the neckline-underarm to back is on the tight side especially if you have large muscles in pecs/shoulder/upper back. But I would rather it be snug and then eventually stretch with use. Wore this to swim practice, happy with it. Bought this because this brand was recommended for durability by other swimmers.

Use the old construction saying of “measure twice, cut once†If you use a fabric tape measure you should be able to get an accurate size without trying one on.

Yo asisto de martes a viernes a una alberca donde se ocupa mucho cloro puesto que reciben a niños y ha sido muy duradero, la tela es gruesa. Realmente cumple con lo que promete. Lo recomiendo al 100 y definitivamente lo volverÃa a comprar.

I bought this because the price was good but when I received it, I found the fabric to be somewhat more flimsy than the identical swimsuit I’d purchased from a swimming store just 2 months earlier. It looks identical but the texture of the fabric is definitely thinner. It’s possible Tyr may have changed the fabric but there was only a two month difference so I am suspicious of the authenticity if this product.

Human hair glued on the plastic hygenic sticker! Tags detached and product on the picture doesn't match the actual product received. Will return and will not order online again!
