A great pair of jeans (or several) is a wardrobe staple. In the words of Yves St. Laurent, fashion designer extraordinaire: I have often said that I wish I had invented blue jeans: They have expression, modesty, sex appeal, simplicity—all I hope for in my clothes.

Jeans are amazingly versatile and ‘blue’ is definitely not their default adjective anymore. The spectrum of patterns, colors, and innovative denim configurations is virtually endless these days. Whether you’re wearing super bright skinnies or slouchy boyfriends, it just takes a few strategic accessories and a sexy shoe to transform your sporty day denim into a sexy evening look.

For a little style inspiration on how to dress up jeans, we’ve come up with 15 easy ways to take your look from day to night.

1. Swap the white button-down for a slinky top.
Layering is key—wear a camisole under your day look and swap the button-down for a sheer blouse or just the cami if it’s warm out.

2. Throw on a tunic for a mod ‘60s vibe.

3. Slip on a slim tuxedo jacket.
A subtly embellished, fitted tuxedo jacket over a white tee is cool, sophisticated and sexy. There’s no better way to own your womanhood than to borrow from the boys on occasion.
