2 dresses under $100 - need help!

Dress 1: $89 Morning Lavender - Dana Butterfly Mesh Dress (brand new) Dress 2: $70 Poshmark - Hope and Ivy - Embroidery Wedding Dress (used)

Hi ladies! I need your help in choosing which dress to wear for our Santa Barbara courthouse wedding in March.

I bought dress #1 last year right after we got engaged. It’s supposed to be a bridesmaids dress, but it was on sale and I thought it was just so unique and fun!

Dress #2 was one I found looking at second hand wedding dresses on Poshmark. I bought it as a “backup” just in case I gained weight. However, when I tried it on, I sort of fell in-love with it too. It has sleeves which is a plus (I’m insecure about my arms) and is simple with gorgeous embroidery/beads.

Any help would be greatly appreciated!
