Bridesmaid officiating

I think that would be fine! they would need to walk down the aisle first though just because an officiant can announce stuff like please turn off phones, etc.

I think it could work out logistically, but heads up--there's a reason that there is an existing business of officiants for hire. It's definitely a job. It requires a bit more certification, "training," and meetings with bride/groom than your typical maid of honor speech. I've seen this happen with a friend of mine that was asked to officiate... it can be a lot to put on a close friend, especially one that isn't a professional. Even someone who's good with public speaking (the friend I mentioned) can really struggle with officiating. Just something to keep in mind.

We have a friend who has officiated for other friends while being in the bridal party and it worked out just fine. I agree that it can be much more personal. We discussed having everyone in our wedding party do a reading or a portion of the ceremony, and now the friend we decided to have officiate may not make it so we may be back to that.
When I talked to my mom about it her concern was if it was legal (yes, in CO we don’t need an officiant at all), and if they understood the difference between a best man/maid of honor speech and officiating 🙄.

One of my bridesmaid will be our officiant!
I’ve been to a wedding before where the best man was the officiant and it went really well.
