We did a couple of different looks (with another studio):
One was formal DH in a blue shirt & slacks, I was in a floral dress and DD was in a bright fushia dress - this one looked the best in photos
Next look was a white shirts/t-shirts and denim jeans (DD had a denim skirt) - looked the least favourable
And the last look was more smart casual - I wore black 3/4 pants and a silk bold floral print top, DH wore a black shirt and black denim jeans. I can't remember what I wore. - Was ok
