Which dress for the evening do of a wedding?

I posted in AIBU, panicked, and now I have two choices

Dress one:

Dress two:

Planned accessories are the blue bag and shoes linked.

Which one do I go for?! It’s a distant relative’s evening do at a mid-July wedding. We’re due for a heatwave so I don’t want to be massively covered.

I will wear my hair down in loose curls

I agree dress one is very casual. However I dislike dress two. Due to the way dress two hangs, I can’t think of any body shape it would flatter. If it’s a choice between these two then I’d go for dress one and style it with accessories.

Dress 2, love it!

I sweat like a bastard in most man made fibres and get really itchy in wool. Its not that unusual!

Dress is a bit casual but nice- dress 2 is awful and looks cheap. I do love your shoes and bag tho and they'll dress up the yellow dress
