Help! Wedding guest dress

[Fedupwithitx]

Hi all.
Attending a wedding this summer. I have both dresses, but the long one is less flattering and also worried there's too much white? The short one, wondering is it too short, not dressy enough, I'll be going to the church and all day celebrations, would really appreciate help!!!

Neither say "wedding" to me
Green far too short, looks quite see through in photos
Other looks nice for going to the pub or lunch with friends

Long one you could dress up a bit with great heels, earrings.
Short one is far too short for a wedding (or anything, if you’re me 🙈).

I voted neither!
The long one is best if you can't get anything new, the vicar would faint at the sight of the green one😆
If you go with the long one it needs jazzing up with some nice jewelry/accessories.
