Ha, Suz, you are so right about the back fasteners being a godsend. I still remember getting stuck in a sports bra in the fitting room at City Sports!
I do actually have another Moving Comfort bra (a Juno, I think) that is actually more supportive (not that my C cup really needs it) but has no back hooks, so I feel like I'm always going to dislocate a shoulder taking it off. FWIW, I put the Fiona on over my head (with the hooks already done up) but I unhook them to take it off.
My one tiny quibble with the Fiona is that the shoulder straps are adjustable with velcro, so you have to be careful to line up the velcro just right, otherwise it scratches. But the velcro is very sturdy - I've never, ever had the velcro come unstuck, not even in the wash.
