What Should Shelly Wear to Her Wedding Shower?

My wedding shower is this weekend! My friend who I've known since kindergarten is hosting it with her mom at their house. I'm really looking forward to celebrating with some of my close family and friends. Although, I'm still trying to decide what to wear! It's going to be HOT this weekend so I'm assessing which option will be best. Here are some of the outfits I'm thinking of wearing! Let me know what you think!
