HELP! for a date

Hi everyone! Let me know if there’s a better place to post this. I’m going on a first date in a couple days and I’ve had a hard time figuring out what to wear. He planned a really cute date. We’re getting lunch at a pretty casual place I picked out, then kayaking at the beach. This is a great date for us and I’m excited!

The outfit has to be good enough for a first impression at lunch but practical enough to kayak in as well. It’ll be like 70 degrees. I do not plan on wearing a swimsuit as it’s a first date and I’m uncomfortable with that. I don’t think he’ll be wearing one either. Maybe a more athletic vibe?
