I receive many compliments for this sexy one piece. I wouldn't mind purchasing more in the future

I purchased this suit in an 18 (XL) as I am a 32D. I'm 5'5" and weigh 200. I wear a size 14 jean. As you can tell by my measurements, neither my bust, or tummy are tiny. This is part of the reason why I needed a suit for a longer torso. Bust: 45.3; Waist: 35; Hips: 46.5"; Upper thigh: 25.3" This swimsuit fitted so well with my chest and my body. 
 The suit is very well made and the stitching is solid. It's also more comfortable to wear and adjust with a suit that has an underwire. I researched suits on the TYR site, another generic swim store online and on Amazon. I also tried on the Sonoma Square Neck suit in a local sports store in an 18. It seemed a tad roomy, but the lack of adjustable straps made it a no go. From what I can tell, this particular suit is not sold in stores, bummer that you can't try it on. Regardless, order it, you have nothing to lose, returns with Amazon are easy. If you're really unsure, order 2 sizes and compare with a full-length mirror.
