I think she looks stunning in bright colors so it's the Zac Posen or the Valentino for me I chose Mr Posen!

i love all of them alot. they are all so simple and chic. but i chose the navy one. i adore the details and the updo.

this was really hard to choose but I chose Zac Posen

zac, far and away. valentino a somewhat distant second.

That Zac Posen dress is AMAZING.

I thought the Valentino Red was a real wowza. The fuschia design was a little boring to me.

The Zac Posen dress accentuates her figure perfectly.

I love the fuchsia Zac Posen on her the best

I really like the pink dress on her.

I love them all! She's gorgeous in the Zac Posen, but I voted for the navy because I love the interesting back.

Wow! I wish I had ALL of these dresses. They are all so beautiful. The Zac Posen is my fave followed by the navy gown with the black beading.

i love them all but i guess the 1st one

I think she looked really good in all of them especially the pink and red but I had to go with the red cause it's totally her color! She looks gorgeous without a doubt!

I like them all..I really like the Zac Posen dress & the purple Derek Lam..& of course, the red..but that's because red is my favorite color

I like the blue!

i'm not a Jennifer Garner fan, but she really does look amazing in all those dresses, and the Zac Posen fits her beautifully, so pretty

Zac Posen dress. Not everyone can pull off such an intense colour.

That Zac Posen dress is unbelievably gorgeous and Jennifer looks radiant in it.

I love everything... especially the current one, the white tailored dress with coral reef and seahorse design. WHO is her stylist? Amazing.
