It’s totally up to you. Whatever you’re most comfortable in. Personally I don’t think there’s anything wrong with you being taller than your husband in pics (or in real life, for that matter!) but you’d rather not be taller, then rock those flats!
I’m a little taller even in flats so I wear heels most of the time. I’m planning to wear a lower heel for our wedding just for comfort. Wear what makes you feel great, but I wouldn’t choose flats only for the height difference.
I'm not tall but I'm doing slippers! Isotoner sells them on Amazon prime for around $13 a pair! I ended up getting my girls the same slipper but in a different color!
Sooooooo comfortable and it would make you not taller than FH if that's what you want!
My fiancé is about an 2 inches taller than me but, I don’t want to wear heels. I’m more of a converse/sneakers wearer so I bought some really cute white lace sneakers that I’ll wear the whole day. You could always wear heels for ceremony/pictures and then change into sandals/flats for reception. My friend did that, she wore like 4 inch heels and as soon as we got to reception she changed into flats.
