Which dress for baby shower?

My shower is coming up and I can't decide which dress to wear. I'm having a little girl and the shower is a fall theme with pink and gold. Do I go a little more dressy with the white lace or the more casual short option? Help me out please! 🤗

PS. I just got a hair cut so my hair is short now like the first picture!

***Thank you so much ladies for your suggestions! I really appreciate it! I think I will go ahead and wear the shorter dress for the fall theme and the long white for maternity pictures. ❤️
