Since my early teenage years I have made collecting lingerie ( for noone but me, myself and I! ) my weird hobby number one – They're just so prettyyyy! I could never really decide if I prefer the bras which close at the back or the front. I would say I almost prefer the back ones mainly out of habit but some of the ones that close at the front just have such a cute back design it's really hard to decide :/
I think like you I would instinctively pick back out of habit but as some of the others said I probably would not care by which I mean if the girl is comfortable and happy in it that is the main thing , if it is visually pleasing to you as a man it is a bonus not a dealbreaker. So in your poll I picked C as closest to my opinion.
I honestly couldn't care less. It's all the same to me, seeing as how I clip together my bras first, then put them on like a t-shirt. (I've recently gotten into collecting cute or sexier pieces of bras too. Nasty habit, crazy how expensive some can get but... what's a girl to do! :P )
I love padded bras because well, you know. I heard VS's push up bra was great but tbh they make your boobs look fake, or that could have just been Kylie lying to us about her plastic modified "over-the-shoulder-boulder-holders". The clasp at the front definitely would make it easier but the back is just way more common and I just prefer it.
Almost all of mine hook in the back. Front hook ones seem to come undone occasionally and don't have much adjustment. Front hook is nice when you are wearing something you dont want that bump in the back.
