These stylish girls know a wide-brimmed hat looks super cool and hides a multitude of January sins under its generous shade. The key to working it? A simple combination of an oversized top to balance the brim (whether it's a shirt like model Lily Aldridge, a baggy knit like blogger Lisa Dengler from Just Another Fashion Blog or supersized faux fur like Made in Chelsea alumna Millie Mackintosh), plus skinny trousers or jeans. Stick to these fail-safe proportions and you can't go wrong. Win win!
