What a change! A look back at Amanda Seyfried’s style evolution

Actress Amanda Seyfried turns 29 today, and though we're not sure what she's got planned for the big day, we're sure she'll be looking divine!

The star has had a bit of a bumpy ride along the road to finding her perfect style, but she's come a long way from the days of wearing jeans on the red carpet.

Let's take a look back through the archives…

1. The outfit that started it all…
"I'm a mouse, duh." Thank you, Mean Girls for this iconic moment/outfit.

2. Her first foray into red carpet glamour
Amanda definitely tried hard with this outfit for the 2005 MTV Movie Awards, but the fit is just a bit all over the place.

3. Uh-oh.
What happened to the turquoise dress? Jeans and flats were a step too far down the "smart casual" road for this 2006 appearance.

4. Wait a minute…
This is more like it! We knew she had it in her!

5. We're loving this high fashion look
Amanda killed it at the 2009 Golden Globes in this one-shoulder pastel number.

6. Very sleek!
Louis Vuitton was a great choice for this 2010 event – Amanda is looking simply stunning here.

7. A bit of a wobble?
The actress' dress for the 2010 Academy Awards was criticised for being just too much for her small frame – some even said it looked "like a roll of bubble wrap." Well, we think she looks fab.

8. Back to the drawing board
This aquamarine blue dress is just a bit too bright for Amanda's pale skin, and the shape's a bit off too. Well, we all make fashion mistakes.

9. WOW.
Look at those pins! Amanda looks easy and elegant in this two-tone playsuit for an appearance on Live With Kelly and Michael in New York.

10. Finally, the style queen emerges once and for all
Amanda got it 100% right in Alexander McQueen at last year's Oscars. It's been a long road, but now look at her!

Happy birthday Amanda!
