Single-cut shirt with single-seam construction and associated methods

A method of manufacturing a shirt, comprising,

• cutting a continuous tubular fabric along an outlined pattern;
• forming a single textile panel which includes all defined shirt portions in a continuous, unbroken piece without separate fabric sections when the continuous tubular fabric is cut along the outlined pattern;
• folding the single textile panel along a shoulder fold;
• aligning a front portion with a back portion when the single textile panel is folded along the shoulder fold;
• creating an upper structure of the shirt when the front portion is aligned with the back portion;
• and
• forming a single continuous seam that extends from a first sleeve to a second sleeve,
• wherein the single continuous seam begins at a sleeve edge, passes across the back portion, and terminates at an opposite sleeve edge, and
• wherein the single continuous seam joins the front portion and the back portion of the single textile panel to form the shirt in a final assembled form.
