Okay kiddo, a halter top is a type of shirt that is kind of like a tank top, but instead of having straps that go over your shoulders, it has one strap that goes around the back of your neck. It leaves your shoulders and upper back uncovered, which can be good for hot weather or if you want to show off your pretty shoulders. Some halter tops tie behind your neck, while others have a clasp or button to fasten it. They can come in different styles and colors, and are often worn with shorts or skirts in the summer.
