i love her.
but i hate that.

Love her, but it's just too much

Blair would not approve.

Leighton is my girl crush. I love the shoes so much. This is so ridiculous, I can't not love it. Amazing.

Is Posh wearing those same shoes? The heel is VERY 90's...

that is so not her style I thought she would of did some classic old hollywood

Poor girl. Does she not know how bad this looks?

i'm ok with this. it's a costume gala after all, so why not wear something funky and crazy?

This? Is ass. But props to the girl for taking a chance. I hate it, but I love that she did it.

Hate it. Kudos for being brave enough to wear this to the Met.

I kind of hate it but I kind of really love it too! But her new hair colour is awful!

shideous

that outfit is hideious and i don't like her hair

What a shame. I really love Leighton's young and fresh look, but her outfit is not only unattractive, but also manages to make her look larger than she really is. I feel like Leighton should dress to show off her beautiful figure. This Emanuel Ungaro dress from the Spring 2009 show is a fun, yet flirty dress!

This is horrible! I can only imagine what Blair would have to say about it.

wish she didn't change her hair colour and was more like Blair in fashion choices

those tights!! NOOOO

i think she looks like an idiot.

WTH Blair would be dissappointed

I think she looks cute...

Very avant garde...

very clownish..sadly. i hope she knew what she was doing. unflattering

that outfit is just too much. perhaps without the legging it would look fab.

it's quite out there with the patterned tights but the shape of the dress is stunning. Kinda crazy, i wouldn't wear it but i think i like it.

I think I just puked in my mouth a little...

That sh*t is freaking awesome! Go Leighton. I knew there was a reason I liked her

omg!! wth is she wearing!? WHO dressed her!!? oh poor girl its tragic too many things i even got a lil dizzy!!! yikes!

whatevaA... i still like her!

i love the dress, i don't think the tights are for me. BUT I LOVE HER!

who ever does not like this ensemble, cannot appreciate true haute couture fashion. stop hating on her, it's absolutely brilliant!

the whole point is to be avant garde...she wouldn't wear this to a movie premier. But since this is the costume gala..she can get away with it. good for her.

the entire point is NOT to look like another pretty idiot in a pretty dress.

she looks cool.

Avant Garde doesn't mean ugly you can be artistic and wearable it's not that hard. I like the leggings I think if they were paired with a simple top at another even with a cool leather jacket she would get all A's

I love the shoes... I wish her hair was still dark and not as costume-y that may save the look. Also the red lipstick... her make up and hair should have been more simple for such a crazy look. She isn't as bad as Madonna though....

BAstyle--art is subjective. This could be pretty and avante garde to others.

Awful!
I think she has the same shoes on as Victoria Beckham.

wtf is she wearing? She looks like a clown.

I love that she took a chance and tried something different. I think the dress/tights apart would be a workable piece outside the Costume Gala too.

ugh no

Kudos for being brave, but man that's an awful dress.

omg! what was she thinking!!!!

i admire her taking a risk.... but unfortunately i don't think it's paid off.

i agree that perhaps the dress without the leggings could've been quite cute.

i love leighton and blair is my current screen idol! but on this occasion she's just missed the target.

she usually looks so amazing. this is disappointing...

to be fair...clashing is all the rage on the catwalk...but on the side walk...ye it looks kinda crap...even if that side walk happens to have red carpet all down it!

I LOVE this!

It's thrillingly hideous, the cut and shape of the dress is brilliant, and most importantly of all, she totally pulls it off.

It IS the costume institute gala, after all...she obviously took the event name as a challenge.

Horrible! I saw another pic of her straight on from the front, and it looked like she had a huge butt coming out of her front. The pattern and colors are also awful.

Absolutely fabulous! Much better than Blake looking cheap in Versace.

rule of thumb - not everything LV is a winner. madonna has shown that to us

Leighton, Leighton, Leighton....

Leighton, please don't ever wear this again.
