Which dress?

I am going to a formal wedding next month and I’m having a hard time picking out a dress. 🤷‍♀️ I’m shopping online because I live in the boonies. 😂

I also want to wear something that will compliment my 1-year-old daughter’s dress. She will probably be wearing this:

I am 5’1”, about 90 lbs, and I don’t really have any “curves.” I’d love to wear a long gown, but I’m too short and don’t have time/money for alterations. These are some of the dresses I’m thinking of:

1. (Not me in this photo)

2.

3.

(Ties in the back)

4.

5.

Do you think any of these would work for a formal wedding? Or should I go with something completely different? HELP!
