My favorite thing about layering is how it can be used to warm up summer pieces so that they're cold-weather ready, or to temper those special items in your closet that you wish you could wear everyday, but are just way too dressy (or skimpy). The trick? The hardest working workhorse in your closet, the button up shirt. While a button up shirt, when worn in a straightforward way, is hardly groundbreaking on its own, when worn underneath something (a dress, sweater, or another shirt), it can turn essentially any neckline into something truly unique.
I'm wearing my current favorite button up here with a dress that I would normally save for a special occasion, such as a cocktail party or holiday fete - and when worn together, this look becomes apropros for the office, date night, or even just an everyday look (I'd pair with sneakers or flat slides for day).
