Sandra is usually a red carpet knock out, but this greasy, frizzy, I-came-here-straight-from-the-gym ponytail is just plain awful. When classic looks are more your thing, stick to what works, no need to get caught up in trends.

Best Defined Brows: Sienna Miller
Everything about Sienna's red carpet look here is stunning, but we give her extra kudos for showing how defined brows don't have to look forced and unnatural. A little strategically blended powder or pencil can enhance your brow shape and your overall look.

Worst Defined Brows: Megan Fox
Unless you want to look like a cheap pin-up girl knockoff (sorry Megan!) don't dramatically define your brows with a stencil, heavily line your eyes and wear candy apple red lipstick all in the same night. It's just too much.

Best Statement-Making Hair Accessory: Eva Mendes
Lovely Eva shows how a big hair accessory can be a great alternative to jeweled earrings and a necklace (and a heck of a lot cheaper!). Paired with a casual ponytail, this headband totally completes her look.

Worst Statement-Making Hair Accessory: Paris Hilton
Remember what we just said about a blingy hair accessory being an alternative to other jewels? Well, we guess that rule doesn't apply in Paris' world. If the stars weren't already blind, they will be after seeing this ensemble.
Red lips, statement-making hair accessories, tousled waves and defined brows are some of the most copy-worthy trends of the season. But just because they're trends doesn't mean everyone should try them -- as these celebrity photos prove. See which A-listers mastered the looks and which ones should stick to their classic hair and makeup styles next time.
