Very nice jersey , well made. However, runs very tight. I went up a size, still snug but not overly tight. My weight is 121 lbs, 5 ft 7 in, and I usually wear a medium. Tried a medium, but way too tight, like a second skin. It is a beautiful well made jersey, just runs very tight.
This jersey is very well made and the fabric is fantastic. Keep in mind the jersey is a very tight fit (like a second skin). I normally wear a medium, 5 ft 7 in, 120 lbs. This jersey was very tight, hard to zip, it fit but very, very tight - the fabric does have a lot of stretch to it. I ordered a large and it was a perfect fit, still snug but not so tight it was like a second skin. My recommendation would be to go up one size from your normal size, unless you like super tight, like a skin suit. However, the jersey is a very nice jersey.
