paris hilton wore a diamond flower headband in 'my new bff' where can i buy that headband?

Although I could not find the headband that Paris wore on My New BFF, I found some great flower headbands that you might also like. I was unsure of your budget so there are some high end and also some real bargains. I hope I found something that will work for you!

       These might not be the exact but you can find some stunning ones by Glam for less on links below! They have more on the first link. Nice! ; )

The majority of their  headbands are not brand name designer headpieces.  They custom manufacture “design inspired” headbands which closely resemble the photographs but include signature design elements unique to the company.  The images shown are reference photographs to illustrate the basic design and cut of the headband. 
As we all know, Paris Hilton loves her headbands. Today, March 19, 2009 at the Paris, Not France Cocktail Party at the 3.14 Beach during the 62nd Cannes Film Festival, she wore a floral print floor-length dress and accented it with a glitzy headband and necklace.

Her look was a little bit hippie-chic and a little bit glamour chick all rolled into one. Hippie style headbands are really popular and being worn by many celebrities these days.

Like with most trends, I recommend you don't over do it. Ease into it gently by picking one statement piece rather than dressing head-to-toe with a Bohemian style dress, hippie headband, fringed bag, beaded necklace and platform espadrilles.

Paris definitely has been wearing an assortment of headbands since arriving at the Cannes Film Festival.
