Women's apparel has come a long way since then. Women's jerseys are now cut to fit a women's body.
Women have a much shorter torso than men requiring a shorter jersey length.
In order for the jersey to fit without billowing, women's jerseys need to be cut to accommodate a women's breasts, taper in at the waist and then fit the hips. To achieve this curvaceous effect, you usually see that the women's jersey has more pieces than the typical mens cut which is just a front and back. Fabric Most jerseys, even the one's that look and feel like cotton, are made of polyester or a polyester blend so that they have the ability to wick moisture and breath. Although cotton breathes well, it retains moisture. Wearing a cotton T-shirt under a bicycle jersey totally negates the function of jersey.
