What makes a good business suit? Is it the cut? The fabric? Maybe the shoes or accessories? With business attire, sophisticated neutrals act as the backdrop to a professional outfit. By investing in a few key suit pieces, you can build an entire work wardrobe. Once you have the essentials, you can be creative with accessories, hosiery, shoes and bags.

What are the essentials? Express has women's suits that work for any office environment. With their selection of blazers, blouses, pants and skirts, they offer the building blocks of the perfect suit. With a palette of neutral colors, you can buy a few pieces and easily mix and match to create a larger work wear wardrobe.

Start with a Blazer: Express Studio Stretch styles have two-way stretch which hugs and flatters your body. Blazer options are plenty. Choose one with a trim-fit, one-button closure, ruched sleeves or a tuxedo cut. Each one will easily fit into your work wardrobe. A great-fitting blazer makes the suit. Go for basic colors like black and grey, or a pop of red.

Blouses - Show Your Colors: When it comes to blouses, the choices are limitless. Long or short sleeve, solid or patterned, under a solid colored suit, the blouse you choose allows you to change up your look. I love the look of a leopard-print blouse under a solid black blazer - chic and timeless.

Pick Your Pant Style: For years, Express has been known for producing on-trend pant styles that fit and flatter. High-waisted, straight leg or flare, pick a style that you are comfortable in and choose colors to compliment your blazer selections.

The Long and Short - Skirts: Obviously, the office isn't a place for a mini-skirt, but there are plenty of options for various skirt lengths. From knee-grazing pencil skirts to high-waisted midis - Express has got you covered. As with pants and a blazer, keep a few neutral colored skirts in varying lengths in rotation.
