Not sure how it would hold. I don't have any at the moment but if memory serves me they have 3 small holes you sew them on with leaving the center snap hole free. So it's more secure you could always stitch it to a small piece of fleece and use another on the inside of the crochet to sew into.
That way it's less likely to give with the stress of attaching and detaching. Between photographer shoots, the wedding, trying on prior... it's going to get a fair bit of use =)
