Combat boots under my dress?

It's really up to you what you want to do. I wore flats, and my posture wasn't messed up. My only concern with those boots is due to the shaft height and gaping that happens when you walk in combat boots, the skirt in your dress might get caught in it A LOT. I was in a show where I had to wear a long skirt and combats, and I was adjusting the entire time. I'd hate for you to be tugging your skirt out of your boot the whole time

If it's comfortable and you like the way it looks, I say do it! I've also heard the inserts suggestion. A slight heel would probably make it feel more comfortable for an entire day of running around.

I don’t see why not !

It’s your wedding day do whatever you like

Wear what you want.

I think combat boots with dresses are cute and trendy now (I wear that often) but I’m not sure how well that look will age... I could say maybe looking back thinking what was I thinking?! But if you love it do it!

Do white docs! Those are comfy and great for photos too!

If you are having a casual wedding, these are fine. If your wedding is more formal, I would consider something else.
