Are either of these ok for a wedding?

I’m 5”1, big boobs size 10 to 12 hoping to lose a little bit before the wedding.
The floral one I like on but think it might be a bit too casual?
Other one looks fine on but maybe a little dark for a summer wedding?
I do love a jumpsuit but haven’t found anything I like in petite ranges what won’t involve shelling out for a strapless bra which could also prove a nightmare or just uncomfortable on the day.
Im 37 if that’s relevant but look younger, I don’t want to look frumpy which is a challenge with being short and the boobs.

I was at a wedding yesterday. The first dress is similar to what lot of people were wearing. There were also a couple of people there in jumpsuits.

The plain green dress is nice too but it's not very full skirted, so how will it be when you sit down or are dancing? The slightly fuller skirt and wrap of dress 1 might be less revealing. Colour is gorgeous - but then I love that shade of green (and its the colour the bridesmaids were wearing yesterday and looked great!)

I think the jumpsuit flares are too wide for your height 5’1 - you will end up looking swamped.

I will see what my sisters think when they come over, I don’t think the flare is too much as I’m quite top heavy they balance me out but I’m really not a style or fashion expert and look like a toddler has dressed me most of the time.
I have sensory issues so comfort is really the most important thing after looking decent in the photos.
