I need help finding something (bright tights or a cardigan?) for LO to wear with the dress below for our family photo shoot. http://www.ebay.com/itm/Girls-7-CREWCUTS-J-CREW-navy-blue-white-stripe-pockets-pleated-cotton-dress-/401005788026

I am wearing a navy maternity dress with a plum cardigan. DH is wearing jeans and a yet to be decided upon shirt. I was thinking mustard tights or a cardigan, but I can't find anything. I'd be open to other colors. LO wears a large 2T or a small 3T right now. Any ideas?
