There are at least three wardrobe malfunctions going on in this picture, so let's break them down one by one. First, bare legs belong at the beach or at home. If you want to be considered a serious professional, you'll have to deal with the inevitable pantyhose.
Next, skirt lengths for business clothing should be knee-length at a minimum and mid-length at a maximum. Save the micro- and miniskirts for dancing and dates, and use the floor length skirts for formal affairs and galas.
Finally, in addition to paying attention to the length of your skirt, you'll want to be aware of the styling details of a garment. Bubble hems are synonymous with cocktail attire, so if you want to make this look work, you need to swap the skirt for a pencil skirt, A-line skirt, gored skirt or gently flared skirt. Any of these styles are generally the better business choice.
Note: If you insist on going bare-legged, then invest in a high-quality sunless tanning product. These products, when used according to the package directions, provide a natural look, and smooth out and hide imperfections. While they are not the perfect solution, they are step up from not wearing any hosiery. Think of them as make-up for your legs.
