It may seem like a small detail, but the effect a belt can have on your outfit is actually pretty big. They're both functional and fashionable, a little piece that pulls double-duty by adding interest and helping to flatter your figure. They also happen to be one of the easiest ways to take a look from office to after-hours and a perfect way to experiment with the season's biggest trends in small doses. Yes, they really do all that — and they're, well, a cinch to wear. Just watch on to see our must-have belts of the season — from McQueen's sexy, statement-making belt to Miu Miu's glittered and girlie version, there's a piece for every personality.
