Yes, it's still crappy cold winter out, but like the Girl Scouts taught us--or the Boy Scouts we crushed on--it's good to be prepared. So with that in mind, we've already started scoping out our spring outwear picks. At the top of the list, something we've never ever been able to quite master: The perfect trenchcoat--one that makes us look suave and sophisticated, instead of pervy and Inspector Gadget-y. Key to picking the perfect trench: Finding the right length--at both the body and cuff--and details, details, details! Whether its adorable buttons or a sweet lining, trench coats can take any outfit up a classic notch.
