What should I where for our family photo?

I am trying to plan a family photo for my husband, 20 month old daughter and my self. I have purchased a burgundy dress for my daughter that she will where with a sweater that I still need to buy. My husband will be wearing a burgundy abercrombie sweater. My problem is I don't know what to where as I have put on quite a bit of weight and I don't want to look dumpy. Any ideas on what would work I am 23 so I want to dress my age.
