Just received 2 days ago, so I can't assess how well it will hold up in chlorine or sun, but I just about cried with joy when I put it on! I ordered in my normal size (20), and it fit perfectly (offered a bit more room), but I wouldn't say that it runs large; just offers a comfortable, yet supportive feel! I have a long torso and very large bust (DD+)! The 22" length is just perfect! It hits the thigh at the sweet spot (perfect coverage and flare to cover upper thigh and make my legs look more lean! I was shocked how supportive (and lifting) it fits in the bust (and without an underwire)! The wide straps (not adjustable) but perfect to hold the girls up without digging in! It has tummy control that does the job without struggling to get the suit on and off! This is the BEST suit I have ever purchased! It is almost as if it was custom made for my body. After trying on this suit, I got an email from company, offering 60% off certain suits; luckily for me, it included MANY in the Longitude line! I purchased 5 more suits and can't wait until they arrive! I just moved to Las Vegas and bought a home with a pool; even though pool season is over, I will still be in the hot tub all winter and now I can't wait! Previous to this suit, I had to think, "do I really want to struggle to put the suit on"! You will not regret your purchase! All of my expectations were exceeded (including customer service) as I had an on-line ordering issue, that they pleasantly solved for me immediately!
