Something Beginning With 'J'.

It has been quite some time since I have been invited to a party.  So it was very nice to receive an  invitation to a birthday party.  All I need to do is get into my 'Chevrolet' and drive for about three hours northward.  Indeed, remembering the really important bit; to steer my car on the left side of the road.
It is going to be a themed event and I have been asked to dress in something beginning with 'J'.
So what could I possibly wear?  Maybe I could go dressed like I am in the above photograph.  Heck, that way, I could be doing a bit of a double 'J' theme.  I think I look rather awesome as a 'jack' rabbit wearing a 'jacket'.  Yes, it is a rabbit, so please don't go splitting 'hares' over it.
There are lots of options regarding the letter 'J'.  I could be very cheap and go dressed as a 'jumper'.  When I state, 'jumper', I mean as in a 'sweater' and not some guy who goes to the party and just jumps around all night.  I might go as a 'jack'.  Plenty of things start with 'jack'.  Here are some examples.  Jackdaw, jackal, jackboot, jackhammer, jackknife, Jack Frost,  jack-o-lantern, jack-in-the-box.  Or, maybe I could kinda' cheat and go as a jack-of-all-trades and end up looking like a jackass.

The above photograph is another possibility.  One time I left the above item at home.  Not a good idea to play goalie in an ice hockey game without wearing the above item.  I played the best game of my life that night.  Yep, I could go to the party as a 'jockstrap'.

So there are loads of things beginning with 'J'.  I might go as a jam jar; a jester; or a grab a pen and paper and pretend I'm a journalist.  I've even contemplated going as a 'Jack' Russell.  Grab the nearest Jack Russell and slap it on top of my head.  I'm only kidding 'Penny'.  You can come back now.
So I think I've got a few ideas about what to wear at the 'J' themed party.  There is an outside chance that I may go as a 'jacket' potato.  That's right, if you are reading this from outside Britain; what you may know as a baked potato is called a jacket potato here.  See, I'm ended this posting with some useless trivia. Then again, maybe I know 'jack' all.
