Is Your Significant Other Sabotaging Your Style

Before this fashionable actress started dating Ashton Kutcher, Mila Kunis wowed on the red carpet in ethereal creations by Dior and Elie Saab—and even looked effortlessly put together during an a.m. coffee run. But now, she's more apt to be photographed in grungy sweats and many fashion critics have called her out for this newfound laziness. While we love that she feels comfy in her relationship, we miss Kunis' single-gal glam!

After marrying husband Eddie Cibrian, with whom she admitted to cheating on her husband, Leann Rimes started showing way more skin. While there's nothing wrong with being sexy, her cleavage-baring, low-cut tops and barely there bikinis make her look like she's got something to prove.

J.Lo rarely disappoints when it comes to figure-flattering, head-turning dresses. But, after divorcing Marc Anthony—and dating a much younger man—the mom of two has adopted an ever sexier style. Unfortunately, her risqué outfits of late tend to age her further, making us hope she'll re-adopt her sleek, age-appropriate style.

On the flip side, former Gilmore Girls star Alexis Bledel seems to be dressing a bit too old for her age now that she's dating actor Vincent Kartheiser. He's only two years her senior, but the dowdy green frock she wore to this year's Screen Actors Guild Awards would look better on a woman twice Bledel's age.

First came the mom jeans fiasco during her Tony Romo years—which Simpson called one of her biggest regrets. Pregnant with her second child (and engaged to former NFLer Eric Johnson), Simpson seems to be slipping back into the soccer-mom look.

When Evan Rachel Wood began dating rocker Marilyn Manson, she adopted his gothic style. While she has maintained her edge since their split in 2008, her look now is more elegant.

This serial dater traded her girlie look for a more hipster vibe when she romanced One Direction heartthrob Harry Styles. Rather than being a chameleon of the guys she dates, we hope this young singer will soon find her own unique style.

When Sarah Silverman dated funnyman Jimmy Kimmel, her style was almost as laid-back as his, which tended to get her flak for either underdressing on the red carpet, or wearing dresses more suited for prom than a posh event. Post-Kimmel, she looks far more confident and polished.

Mad Men star Elisabeth Moss debuted a hotter, flirtier look after her divorce from Fred Armisen, showing that perhaps he was the one holding her back from shining like a true Hollywood style star.
