What to wear for my small wedding ceremony?

So less then a month I will be getting married to my best friend! We decided to have a small ceremony with close friends and family and have a big reception next year with all our friends and extended family. I have a wedding dress but due to certain situations that have had us postpone the big celebration for a year from now I don’t have it fitted or anything so I just wanna wear something white and cute. Anyone have any suggestions?

Update: I found this outfit and I love it for a small simple ceremony! Thoughts?
