I purchased this item online, used. I bought it because it was listed as "size M." However, when it arrived, although the tag does indeed say M, the fit was very tight, so I don't think I'll have a chance to wear it, and I'm putting it up for sale. This is my first time buying an Armani shirt, so I'm not sure if this is the intended fit, or if it's meant to be worn as an undershirt. Please be aware of the above before purchasing. There are accent stones on the shoulders. The color looks blue in the photos, but it's actually black when viewed in person. Please also check the photos for the condition of the item before purchasing.
