It appears the store wrote over something on the tag.  I believe it says size 28  I tried it on (I am 18-20) and it was big in the shoulders, arms, chest and had room in the belly area.  This is my moms, we are cleaning out her closet of approximately $20K worth of well kept items, many with tags.  Shoes, jackets, dressy outfits of all kinds.  

so I would say this is a 26-28
measurements
across at armpit 26"
collar at neck to bottom of jacket 32"

it has shoulder pads inside the lining
it has white lining :)
it is black and white checkered
3/4 sleeves

This is sold as is- so if you have any questions let us know prior to bidding.
