As soon as I saw the Park Avenue Play Set, I knew I had to have both pieces. I wear an XL in the romper, and stayed with the XL in the top and pants. Be aware the pants are quite long, so if you are wearing them outdoors, you may have to pull them up a bit so they don't drag. I am 5'7" tall. The Marine color is beautiful and the neckline on the top isn't so high that it feels like a turtleneck. I was wearing it yesterday just to run errands and a friend called me for a spur-of-the-moment lunch. I didn't have to run home and change, and even got a few compliments on the outfit! Only criticism on the pants is that the elastic encased in the waistband rolls and folds over. That is not a deal breaker, as this is a great set. More colors, please!
