I like racer-back swimming suits and sports bras because the straps don't slip when you move around, so when I found a regular bra with a racer-back strap arrangement, I figured it would be simply marvelous-fantastic.
Well, the straps sure as heck stay put, but they show through every neckline except for very high crew necks and turtlenecks.
Also, the little hinge arrangement in front that you use to hook and unhook it is difficult to snap together and makes periodic, unpredictable, and slightly unsettling clicking noises throughout the day. I live in fear of my boobies taking a mad break for it when that thing spontaneously unhinges and pops open. I'm sure it will some day.
