Are these dresses appropriate for a December wedding?

[Pinkkahori]

I have a wedding coming up and i have 2 dresses I have worn to previous weddings but they were both summer weddings.
Are these too summery?
dress 1
dress 2
Dress 1 is my favourite.
Thanks

Number one is lovely :) not too bright imo

You'll catch your death.

Too summery imo.
How about something like this
Not expensive, warm and versatile
I've got one in burgundy and it's also very comfortable.

I agree wth pp too summery imo.
Do like the dress @user5656 suggested

Thanks for the replies. Sorry haven't had a minute to respond.
I was hoping not to have to buy anything new.
Decided to wear dress 1. I have a jacket and shoes that work with it but now having doubts.
Don't really have time or money for shopping either.
