Women can often get away with a wider range of attire than men, because let's face it, guys can't wear skirts or dresses. The rule of thumb is to let comfort and professionalism guide you when you're dressing for business casual occasions.
Ask your human resources department for official guidelines. Business casual means different things at different companies. At a large corporation, it may mean slacks or a business skirt; at a smaller company, it may mean a cotton sweater and a floral skirt.
Before you go casual, check your daily planner to make sure you don't have any meetings that require formal business attire.
Select clean, wrinkle-free clothes.
Wear a good-quality blouse or knit shirt. Include a casual blazer or cardigan if appropriate.
Don pressed khakis or other slacks, or a dress or skirt. If a dress is sleeveless, wear a blazer or cardigan over it. Check your company's policy before you decide to wear jeans to work.
Wear shoes that are comfortable and appropriate for your outfit. Funky platform athletic shoes or strappy sandals might be formal enough for some companies; however, it's more typical to wear closed-toed leather shoes. Avoid worn-out shoes.
Keep the makeup light. Let your natural beauty shine through.
Accessorize with a silk scarf or classic bracelet to give your casual outfit a polished look.
A basic pair of black slacks is a must for any work wardrobe. Business casual attire is more formal than weekend wear. Faded T-shirts, shorts, torn clothing and risqué attire are not appropriate.
