What is “a before-and-after piece”?
Great question! When someone says "before-and-after" he is describing the differences that were made due to a specific treatment or task. In this movie, Nigel is asking Miranda if Andy is a "before-and-after piece." He is asking Miranda if Andy is going to be receiving a fashion makeover, and if their magazine will be publishing the changes that were made to Andy. For example, if you watch a commercial for diets or exercising regimens, the company will typically show pictures of the client before she started the diet and after the diet. With "before-and-after" pictures or pieces, you will usually see a noticeable difference of some kind.
