I can't tell you how many times this questions has come up in my life. I've asked it, been asked it, seen threads about it in Facebook groups... It's one question that I think in a way will never fully be answered.
Honestly it has taken me five years to find the outfit that works for me and I'm thrilled to say that at least for now, my days of googling "what to wear to photograph a wedding" are behind me.
It was hard for me to settle on an appropriate outfit for a number of reasons. You want to look nice and dressy because it's a wedding, but you aren't a guest, so you don't want to be too dressy. You are a part of the day's working staff. You also dont want to be confused with the catering staff though, so you need something a little different from them. Dresses work great for some wedding photographers but I am not one of them. For a long time I wore trousers and a blouse, but too often I found myself feeling insecure. A lot of my photographer friends love wearing rompers to photograph weddings in, but they aren't my favorite. Don't get me wrong, they look great!! I just don't love the idea of taking off all my clothes every time I have to bathroom... know what I mean ladies?
Last year I found an outfit that works perfectly for me. It's so simple I really can't believe I didn't think of it before.
First, I start with a black, knee length shift dress. I like 3/4 length sleeves because I just feel more comfortable and more professional. Macy's and Target have great options! Then I pair them with a good pair of black leggings. And by a "good pair", I mean a pair that isn't see through. Fabletics are my go too leggings for this! For shoes I wear these Sketchers GO walk lite shoes in black.
