So like Alley, I too had to dress professionally for a school function. I am wearing this black dress with sleeves and small rhinestones. The dress was purchased from Forever 21. I am wearing white tights from Khol's and the khaki blazer was a gift. The shoes were also a gift from my friends. My purse is Michael Kors and its a Black color. I kept my outfit more on a neutral color palette, unlike Alley. Hope this gave you a better idea of how to dress "professionally".
