Nike Women's Small (3 - 5).  Please see photo of tag with the size for a more accurate description.

There is the letter P written on the the tag. I am not sure if that is for petite or it has another meaning.  I am 5.9, tried it on

and it is a bit small but not by much.  I usually wear a medium. So, that being said seems to be a regular small.

This is a brown, green, gold plaid snowboarding coat. Excellent Pre owned condition. No rips, tears, holes, etc.  It will not look brand new but that being said this is a great looking jacket.
