I think it is so interesting the way that society's parameters of beauty change with time and culture. Sure, Madonna's gap tooth smile became iconic to her, but for a long time, you didn't see young girls forgoing trips to the orthodontist. Now, all of the new 'it' models (like Abbey Lee Kershaw and Lara Stone) are flaunting and even showcasing their gaps. Same goes for Groucho Marx style eyebrows - Brooke Shields got away with it but every girl was still tweezing away. Now, it's en vogue to let your brows speak for themselves - and even give them a little feathered pencil help if you're not naturally gifted with an endowed brow. Fashion for thought.
