A gray suit can seem like an older item in a wardrobe, but with a little attention, it can be styled into a sophisticated look like Ki Eun-Se.

The most basic match is with a white dress shirt. The key here is the fit: finding a natural shoulder line and a fit that suits you. Although it's common to see fashionistas these days choose oversized blazers with wide-fit pants, the most important thing is finding the fit that you like best.

Varying shades of gray can create a surprisingly natural and sophisticated combination. Pair a dark gray suit with a shirt a shade or two lighter. The key here is to pick an inner lighter than the suit. As seen in Ki Eun-Se's outfit, matching with neutral-tone knits or turtleneck sweaters can also create a harmonious style.
Gray suits match well with various colors, allowing you to express your individuality with inner wears and accessories in tones like blue, navy, black, and burgundy. Consider accessories such as watches, belts, and pocket squares. Simple but eye-catching earrings and bracelets can also be a point of your outfit. These accessories can add flavor to your style.
For shoes, black and brown ankle boots, long boots go well with the suit. Oxford loafers, sneakers, or even daring heels can add a sexy touch to the styling.
