Advice on maternity pic outfit?

Hey all! In about a month-6weeks aspen trees will turn gold in my state. Yay! We are doing an early fall maternity shoot. My husband will wear black jeans and a red plaid shirt. I have no idea what I should wear though! I want to look great, but the big ball gown-like maternity dresses. I also don’t know what color! I have strawberry blonde hair so I look great in green, but I don’t think that’ll go with the red. Any advice is welcome!
