It includes a DOUBLE BREASTED suit jacket in about a 36 made of 100% wool (has 3 small moth holes in it on the back, see last pic for reference). The vest is a size Medium and did fit perfectly.  It does not have the customary adjustment belt on the back of it. (There are 2 shirts. One was a bit yellowed and didn’t whiten back up after laundering so I went back and got another a lot whiter. {BOTH WILL BE INCLUDED})White shirt is a size 16 16 1/2 slim fit. (the one that is a bit yellowed is a 15-15 1/2). Pants are a size 36 x 30 (I did put a stitch in the back taking them up to about a 34”) The hat is M but can be adjusted with tissue in the band to make it smaller. The shoes are a size 10 and fit his size 9 1/2 pretty well. The get up even includes the tie and hankie in the pocket. 

I mean this is a “COMPLETE” costume
