This step is crucial to the fit of your clothes, and many people don't notice this. Most clothes and pants look great from the front, but often look terrible from the back. This is the time to take your front camera phone to the fitting room and check how the back of the dress looks on you. See if it looks baggy or too tight. Turn around so your back is facing the fitting room mirror, switch your phone to front-facing photo mode, and hold it in front of you, above your shoulders and tilted slightly downward.
