Although it is too big, my lover really likes this shirt, he lives in it lately. It is very light but keeps you warm on cool nights. It is one size larger, even if it is one size smaller, it is too big. It's not tight, it's loose. It is comfortable to wear and the fabric is comfortable on the body. We've washed it twice already and it's holding up well so the quality is there we expect this shirt to last quite a while.
