Our Club fit bike jerseys are comfortable and RELAXED for Regular Folks! There is no elastic around the bottom. Most people go by the first CHEST measurement on the charts. The Mens (unisex) are simular to a standard men's t-shirt size.  NOTE:The Womens style are not quite as "relaxed" as mens style -so size up one if you prefer it not snug.
