It breaks

Emily continues to fiddle with the straps trying to do her bikini top back up, but to no avail, in fact it suddenly feels looser.

Bringing her hand back around in front of herself, Emily looks down to see the strap hanging loose, no longer attached to the bikini.

Still holding the bikini to her breasts with one hand Emily once again looks around the pool area, feeling horribly exposed and spotting at least two or three people staring at her. If she moves again there's a good chance she'll completely loose her bikini top. There's a spare in her room at least, but she still needs to get there.
