Hook up your look with hip but mature threads that suggest a professional demeanor without shouting for attention.
Step 1: Choose suit, shirt, tie
Choose a sport coat, blazer, or suit in a subdued color and current style. Combine this with an open-colared shirt or a tie.
Be sure you understand what the company rules are for casual dress. High-level casual is more dressy, for instance, though it still may not require a tie.
Step 2: Choose shirt
Wear a clean, quality cotton, collared shirt. Alternate with fine gauge knits free of wrinkles and avoid shiny, silky fabrics and wild colors and designs.
Step 3: Choose sweater, change suit
Wear a stylish but understated sweater, or change the look of a suit with varying patterns in the shirt or tie you wear.
Step 4: Choose pants
Sport clean, pressed slacks, corduroys, khakis, and sometimes chinos in the right climate. Avoid shorts, jeans, or anything with ragged edges or hanging threads.
None of this will matter if you forget that "casual" doesn't include letting hygiene or manners lapse.
Step 5: Choose shoes and belt
Wear leather shoes, clean and polished, and a matching leather belt. Basic dress boots are better than hiking or athletic boots unless the office is full of gamers, geeks, and burn-outs. Leave the sandals and flip-flops at home.
Step 6: Choose socks
Slip on comfortable, dark, mid-calf length socks that blend well with your pants, so that when you sit or cross a leg no skin shows. Patterns like argyle are fine if they don't clash with stripes, plaids, or other designs in your pants.
Step 7: Trim hair
Trim your hair so that it looks groomed, even if you prefer the bed-head look, which can look almost intentional with a little product. Facial hair is all right if trimmed, neat, and acceptable in the industry or to your company.
Step 8: Avoid accessories
Avoid accessories beyond a watch and a wedding ring.
