It won't fit any more.
Several years ago, prior to meeting Atilla The Cheerleader, I bought a swimsuit. It's green, with a square neck. It fit three years ago and looked okay, actually.
Then I got lats. And shoulders. And pectoral muscles. And my legs went all square and muscle-y, and I got biceps. The belly's still there, but I look more fit.
And the swimsuit? Holy lord, it *so* does not fit any more.
Square-neck suit + big lats + impressive shoulders + pecs that are things of beauty = Jolly Green Gumball.
I have ordered a plain black V-neck from Land's End. Humph.
