Gretchen Weiners, played by Lacey Chabert, taught everyone the rules of the Plastics: on Wednesdays, we wear pink. 

She also advised us not wearing a tank top two days in a row and only wearing your hair in a ponytail once a week. But in real life, the star seems to be a lot less strict when it comes to fashion. Her sweet and flirty style incorporate all colors and prints. Plus, Lacey can pull off any silhouette from the summery yellow empire-waist frock to her most recent look at the Hallmark TCA event where she wore a feminine purple A-line dress.

Here's a bonus: Tina Fey a.k.a Ms. Norbury. 

We were first introduced to the now Garnier skincare spokesperson when she starred on Saturday Night Live in her signature glasses and Weekend Update blazer. But she made some major updates since then—constantly impressing us on the red carpet especially during award seasons. She's worked with stylist Anna Bingemann and continues to team up with current stylist Cristina Ehrlich for show-stopping looks including her red Oscar de la Renta lace gown at the 2011 SAG Awards. 

Ehrlich shared, "Tina is a petite woman, and it's all about how things fit her. We do try to mix it up, but it's always from the mentality of a corseted feel or a fit that shows off her curves. We err on the side of sexy. Besides, the thing about Tina is that her fashion is going to be strong, but her humor is going to be stronger." The two time Golden Globes co-host looked great both years wearing designer gowns by one of her favorites, Carolina Herrera. Most recenly Tina wowed us in an Antonio Berardi dual color dress at the Los Angeles premiere of Muppets Most Wanted.

In her 2011 best selling book, Bossypants, the multi-talented actor and writer talks about her history with fashion. "Anyone who has never met me can tell you that fashion has always been very very very very very very very important to me. Don't concern yourself with fashion; stick to simple pieces that flatter your body type. By 19, I had found my look. Oversize T-shirts, bike shorts, and wrestling shoes. To prevent the silhouette from being too baggy, I would cinch it at the waist with my fanny pack. I was pretty sure I would wear this look forever. I was nailing it on a daily basis. Find something like this for yourself as soon as possible."
