(Cover) - EN Star Style - Whitney Port gets worried about being overdressed.

The reality-television-star-and-fashion-designer has previously contributed to Teen Vogue, as well as working for Diane von Frstenberg in the past, so she knows a fair amount about style.

Despite her expertise, the 25-year-old admits she sometimes fears her passion for glamour makes her look too dolled up. An example of this was the recent premiere for Justin Bieber: Never Say Never, a new documentary charting the adventures of the teen pop star. Whitney looked stunning in a sparkly Vince top and a skirt from her Whitney Eve collection teamed with Balenciaga shoes and Miriam Haskell bracelets, although she felt anxious about her attire.

I was actually nervous before I got there because I thought I was going to be overdressed, Whitney confessed on her blog.

The star had no reason to worry though, as she fitted in well with the other glamorous celebrities. A-listers ranging from Miley Cyrus to Usher and Selena Gomez were present, and everybody had made a big effort in the style stakes.

Once I arrived I saw that everyone was decked out so I felt better, added Whitney. (C) Cover Media
