bra hooks

[LadyB49]

I am wearing a 38h full cup bra fitted in store, Bravissimo Melrose.
Definitely needed the 38 band. Fits perfectly.
After several wearings it's now on the tightest hooks -three hook fastening..
But always, by the end of the day a least one hook has come undone.
Any ideas why this would be?

Possibly the clasp on one of the hooks is too loose and when you are moving it is coming out? Have you tried bending it back a little to make it hold a little tighter?

Duuh....how dopey am I.
It happened also on other bras.
I'll give them a tweek.
