S&S Activewear—Van Heusen Ladies' Easy Care Wrinkle Free Royal Oxford Shirt
There's really no trick to this belt trend. There are two different ways to do it. With tunic tops (those that hang straight down from the bust), you want to "create" a waist so it doesn't look like you're in a potato sack. In these cases, cinching is OK. However, when it comes to buttondowns, make sure the shirt already skims curves. The idea here is to accent the middle. This shirt, for example, has darts on both the front and the back so there won't be any unflattering bunching or bulging.
