Engagement photoshoot dilemmas (outfits + activities)

I’m probably overthinking this as I do everything but here we go.. Our shoot is in a week at the beach. I bought a red maxi dress for the pictures (i’ll attach pics below of all the outfits i’m discussing in this post). We have an hour for the pictures. When I spoke to the photographer to finalize details she suggested bringing 2-3 outfits - one being jeans and a casual black/white shirt for the more laid back pictures and water pictures. She suggested bringing champagne bottles to pop, blanket for a picnic, our favorite drink or snack, any kind of activity like that for diversity in the pictures. I’m not sure how all of this will fit into the span of an hour but anyway...


I picked out a white shirt and jeans for the more casual pictures, however the top is not a getting in the ocean type of top. I want to bring another shirt that I can switch into super quickly but I can not for the life of me picture a shirt that would be cute for that. We won’t be getting fully in the ocean or anything, probably just sitting or laying in the tide lol. Any suggestions for what type of shirt for that? I would choose a dress but I don’t think there will be time for another full on outfit change with a 5 minute walk to our car & back.
