You don't nesecarilly have to wear suits. Do you like skirts? A cute skirt N blouse can look corporate, or if not I have seen some girl's suits that are hella cute. Get a few blouses in the colors you like, N I know this isn't popular to do these days (Looks more corporate N dressy) In its own way, I think this look is just as cute as charecter Tees but just more dressy. It's mega sexy too! I hope you find some outfits you like. I'm sure you're gonna look hot!
Wear either a t-shirt or tank top--solid colors for the t shirt or tank. Wear that with a blazer over it. But only wear a blazer with that with a pair of classy dressy jeans with either high heels or sandals. If your work environment allows jeans on cerain days go with that look-you will have some heads turning for sure.
Hmm, with still being able to wear what you like. Take the cartoon t-shirts and dress it up, wear a blazer over it. (If the shirts have a wide range of colour stick with just a black blazer). Sundresses are great too (:
