One of the distinguishing features of a good bra and top is that they should always be sufficiently spacious to allow plenty of freedom of movement so as to give maximum wobble factor for any set of tits that are fully deserving of such recognition.
I fully accept that this does not apply to exercise bras which are specifically designed for protective purposes.

It's good to have clarified that point belatedly and i'm pleased to have got that off my chest, ( appropriate terminology! )
