As a stylist, one of the questions I am often asked by my clients is "How do I dress stylish for work?". I would advise starting off with a work wardrobe staple such as a pencil skirt, a pair of dress pants, or a sheath dress. You then want to add an on trend or stylish item, maybe bold color pumps, a blouse in the color of the season, or a nice nice scarf. For my outfit I chose a pencil skirt (staple), a stylish but professional graphic print blouse, and bold white heels (very on trend these days).
STYLE TIP: If you're a curvy girl like myself, depending on your work environment, I would go with a thicker material for your skirt or dress. Knit tends to cling the body and accentuates the curves.
