I need ideas for a photo session with my SO and his family!

Hey girls! I'll be the first to admit I suck at picking cute outfits 🙄😂 my boyfriend is a marine, and is on leave for the month, so we're taking pictures together with his family, and I need fashion advice lol. He's wearing his blues, but I don't know what to do. They're gonna be outside pictures, really country and rustic. (If that helps at all lol) and we live in Louisiana, so chances are, it'll be hot😅 I'll put pictures of him in blues and myself (again, maybe that'll help I have no clue) so the full body picture isn't my boyfriend because I couldn't find one of him in his blues lmao but the headshot is him 🤗and full body of me lol
