OOTD Help! (Wedding Edition)

I come to you asking for some help with what to wear for my weekend wedding!!  I ended up pulling two pieces from my closet to choose from - I've had these dresses for a while and they're just raring to go!  (Yep, my dresses are super excited!) Here's some wedding details that might help with your decision making process:

Start time: 4pm Location: Dana Point, CA (right on the water) Invitation specifics: "Dancing shoes required"

My two options are:

LOOK #1 - Long black halter with embroidery paired with black heels

New Dress A Day - What to wear to a wedding - black dress

LOOK #2 - Little Red (Erin Fetherston) Dress paired with aubergine slingbacks

(The camera doesn't do this dress justice, but to get a better idea the skirt is made of a crepe material and the edging at the bust is satin.)

New Dress A Day - What to wear to a wedding - short red dress

Long or short?  Red or black?  Can't wait to hear your thoughts!  (I'll post an instagram teaser shot when I get to the wedding so you can see which one won before the full post rundown!)

Oh and fear not...even though I didn't make these guys, I've remade a bunch of things I'll be wearing the rest of the weekend.
