Mature

Celebs who don't dress their age

Sometimes young stars try to grow up too fast. Sometimes older stars can't ditch the mini skirts. These are examples of each instance.

Can I Wear This?

Can I Wear This?

Whether it's someone like Kris Jenner (left) who just refuses to let her wardrobe mature like her age has or mom of four Heidi Klum (middle) who should cover up a little more, or Miley Cyrus (right), who can't find the balance between frumpy and risque, stars are all sorts of confused when it comes to how they think they should dress.

Mariah Carey's LBD

Emma Stone's floral disaster

Stone looked matronly in a purple floral flock in New York City. The 25-year-old should ditch that look ASAP!

Britney

We're not sure what age is appropriate for Spears' getup. The singer stepped out wearing daily dukes and a bandana-like top. Click here for more pics of Spears from X17online.com.

Kourtney K

The pregnant reality star looked more like almost 2-year-old daughter Penelope in braids and overalls than a 35-year-old mother of two. Click here for more pictures of the Kardashian sister from X17online.com.

Carmen Electra

While there's no denying Electra looked electric in a hot pink number, but at 42, it might be time to retire the bandage dress. For more pictures of Electra, go to X17online.com.

Heidi Klum

The typically well-dressed Klum looked disheveled and way past her 40-years in overalls. Click here for more pictures of the model at X17online.com.

Courtney Stodden

The 19-year-old is known for her proactive outfits which are not appropriate for almost anyone, let alone a teenager. Where did C-Stod decide to wear this little black number? Church of course. She wrote on Instagram, "Church day #blonde #happy #sunday."

Brooklyn Decker

The usually sexy 27-year-old looks more like a shlumpy 47-year-old in an ill fitting capri double breasted pants suit. Click here for more pictures of the actress on X17online.com.

Victoria Beckham

Beckham may be a mom of four, but that doesn't mean she has to completely cover up. The former Spice Girl singer is known for her fashion sense but this outfit definitely doesn't earn her her usual spot on the best dressed list. For more pictures of Beckham, visit X17online.com.

Rihanna

What was she thinking? The 26-year-old singer looked cloer to 66 in her purple suit.

Shannen Doherty

We're pretty sure Doherty is past the age of Daisy Dukes. Sometimes more is more Shannen.

Miley Cyrus

While we appreciate Miley covering up for once, the 21-year-old singer looks frumpy in her black frock.

Kate Middleton

Princess Kate is known for her modest style, but that doesn't mean the new mummy has to dress like a granny!

Adele

Adele's talent is far beyond her years, but so is her wardrobe. Can you believe she's only 25?

Jennifer Aniston

Jen, we get it, you have great legs. But when the pockets of shorts show, that usually means they are too short - especially for someone who is closer to 50 than 30.

Amanda Seyfried

With temperatures surpassing 100 degrees in NY there's no excuse for Amanda to have worn this Bette Midler lookin' number to a taping of David Letterman.

Heidi Klum

A lacy see-thru top may have been apropos for the Victoria's Secret runway, but it isn't exactly mom-of-the-year attire.

Fergie

Fergie isn't even a mom yet, and already her fashion sense is suffering. Give that suit back to grandma.

The 55-year-old actress isn't exactly shy about baring some skin...

The young actress only recently got married, but she has been dressing matronly for years.

Kourtney Kardashian

Sometimes we love Kourtney's stylish wardrobe, but lately the grandma-inspired looks she's been trying out (with her new, shorter haircut) make her look way older than she is.

The former 'Melrose Place' star was spotted wearing a top she may have bought when she was on 'Melrose Place.'

Heidi Klum

Heidi Klum

We get it Heidi. You are a supermodel. But you are also 39 years old and have three or four dozen kids. Come on mom, wear a sweater!

 

Selena Gomez

The young actress is promoting her most recent flick "Spring Breakers." 

Apparently she doesn't want to be viewed as a young partying teen, so she's trying to dress more like Diane Keaton instead.

Kristen Stewart

Kristen Stewart

Cher circa 1990, is that you? 

This one is as much about dressing your age as it is dressing your era. Kristen Stewart has never been exactly what one would call "fashion savvy" but this look is one of the strangest we've seen in a while. It's a fine mix of Cher and Tina Turner, when they were 40+ and still trying to look sexy.

Anne Hathaway

Anne Hathaway 

The "Les Miserables" star doesn't dress like her peers her own age. She's like four decades ahead of her time at the Hollywood Walk Of Fame ceremony for Hugh Jackman on Dec. 13.

Halle is much closer to age 50 than she is to age 20, and although she looks amazing for her age, this is a great lesson: Just because you can wear something, doesn't mean that you should.

The star was born in 1958, there are no circumstances in which her donning a cheerleader outfit are okay. Neither Halloween nor theatrical performances make this look okay. She should stop shopping in her teen daughter's closet.

The former Disney star recently shed some weight, which is probably what makes her think that this outfit is okay. We're not sure if she looks like a kid playing dress up or a 40-year-old exotic dancer.
