The dress should never be dull. Even if you want to jump into something super comfortable, appropriate for a very long journey. Just look at Nina Dobrev (Vampire Diaries). It's enough to put on some charismatic booties, like Deena & Ozzy, to add character to the whole stylization.

These booties are absolutely fantastic. Deena & Ozzy have an eco-leather footbed, while Bronx (surprise, surprise) - made of natural leather. So, as you can see, cheaper doesn't necessarily mean worse...
I also love Nina's hat... If you happen to find a similar one, let me know...
