London, January 15.

The year began with a demure, understated white jumpsuit, accessorized with a bow of hair. A nod to the noted adventurer Alice In Wonderland? Perhaps… But The Lady loves a girlish touch.

Lyrics from Lady Gaga's song "The Fame" seem to fit here:

I can't help myself
I'm addicted to a life of material
It's some kind of joke
I'm obsessively opposed to the typical

All we care about is
runway models, Cadillacs and liquor bottles
Give me something, I wanna be
Retro glamour, Hollywood, yes we live for the
Fame…

Made up like a Columbine from a Harlequinade!

COLUMBINE : Pierrot,
My vinaigrette ! I cannot live without
My vinaigrette!

PIERROT: My only love, you are
So fundamental! . . . How would you like
to be
An actress, Columbine? I am become
Your manager.

COLUMBINE : Why, Pierrot, I can't act.

PIERROT: Can't act! Can't act! La, listen to
the woman !
What s that to do with the price of furs ?
You're blonde,
Are you not? you have no education, have
you?
Can't act ! You under-rate yourself, my dear !

COLUMBINE: Yes, I suppose I do.

PIERROT: As for the rest,
I'll teach you how to cry, and how to die,
And other little tricks ; and the house will love
you.
You ll be a star by five o clock . . . that is,
If you will let me pay for your apartment.

After a long year, The Lady looked lovely in a restrained gown at the launch of VEVO.

And there you have it: Girlish, tough, proper, whimsical, fierce, provocative and experimental, a year of Gaga ensembles makes you wonder what she'll do next. Some say, when it comes to fashion, she is more powerful than Anna Wintour. Regardless: If you made it this far, click here for a message from Lady Gaga herself.
