These made a fantastic addition to my a ravey costume, the clips are strong and stayed on all night throughout my 6 hr dance performance, batteries lasted and it comes with extra set. Really cute and fun way to spice up your outfit. Of note, I let them hang down at my sides, I didn't wear them over my shoulders, so I can't comment as to their suitability for that but since they are adjustable I imagine they would work just fine.
