From Pamela's Patterns:
This is a T-shirt pattern unlike anything you have tried before! It is made for a real woman, and addresses the most common fitting issues we face – high round back, forward shoulder, full hip and bust – and offers a good fit through the shoulder and neck. Design details include an "essence of waist", flattering shirt-tail hemline, three necklines, and four sleeve lengths.
This pattern is sized for a high bust measurement of 31"–45". (The full bust measurement can be considerably larger due to the optional darted front pattern piece.)
