Care Tips to Keep Your Shorts Looking Smart

Wash Smart, Not Hard

• Machine wash cold

• Hang dry—no tumble dryers

• Steam lightly to remove creases

Pack for Travel Like a Pro

Roll rather than fold to avoid wrinkles, and store belts and buckles separately to preserve shape.

Why Fit Matters: The Power of Fitted Shorts

Ill-fitting shorts—whether too baggy or too tight — can throw off your whole look. Here’s what you need to know:

• Waistband: Your shorts should sit just below your natural waist. No sagging, no squeezing. Look for a waistband that’s flexible but structured.

• Length: The modern standard for smart shorts is a 7" to 9" inseam, depending on your height and style. Shorter lengths (about 5") suit athletic builds or swim styles well. They should feel fitted and intentional.

• Tapered Leg: Avoid wide leg openings. A subtle taper creates a streamlined shape and helps elongate the legs.

From Pool to Patio: The Versatility of Smart Shorts

Here’s where smart shorts shine: they adapt.

1. As Swimwear

Our fitted swim shorts double as all-day wear. Quick-drying materials, mesh lining, and hidden pockets let you go from a swim to a smoothie without changing clothes. Plus, if you’re bold enough, white swim shorts — when lined well — can look incredibly fresh and crisp.

2. Summer Socials

Dress them up with a short-sleeve button-down and clean sneakers. Choose neutral tones or classic patterns to keep things elevated.

3. Everyday Errands

Pair with a tank or tee and a lightweight cap. Our Boss shorts — a nickname that stuck because they look and feel that confident — are designed with both form and function in mind. Big enough for your phone and keys, yet sleek enough to not weigh you down.

4. Athletic Flex

Don’t underestimate the power of men’s fitted shorts for light training, trail walks, or stretching at the park. They should allow you to move freely without riding up or dragging down.

Expert Advice: How to Build Looks Around Fitted Shorts

A great pair of shorts is only the beginning. Here’s how to style around them:

• Footwear: Loafers for dinner, sneakers for daytime, slides for the pool. Keep it clean — scuffed-up shoes kill the vibe.

• Top Game: A tucked-in tee or a fitted polo instantly elevates your look. For swim shorts, a relaxed linen button-up adds class without heat.

• Layering: Throw on an unstructured blazer or a lightweight overshirt for cool evenings. Contrast your shorts’ color or texture to build visual interest.

• Accessories: A clean watch, simple bracelet, and minimal belt (if needed) can polish your look. Keep the backpack or sling bag clean and structured — function meets form.
