LADIES, I NEED HELP!!!

I have a wedding coming up in May, I've been working out really hard and am seeing results and know by May I'm going to be looking and feeling awesome. I'm trying to decide between 2 dresses to wear, they're both from Victorias Secret so, of course, in the pictures the models make them look slutty lol....but I usually wear a looser fitting flowy dress and this time I'm going for looking HOT...my husband is going to be a groomsman and I need to look awesome cause his suit it super nice. So...I need your help deciding which dress....


Dress A in red or black...
