I wore mine from the fall of 1971 through the spring of 1974. I'm thinking that the picture of me was taken in the early fall of 1973.
When I was first issued mine (in the fall of 1971) I was extremely distressed, as it was tiny (obviously a "girl's" size...but my Mom soon realized that the uniform had been (for some girl, previously) been all taken in. and - once she let it out - it fit perfectly. I wore the same one for all three years. The quality of the wool was so high that my Mom was completely/100% able to iron out all the creases from having been taken in (zero evidence).
At football games (at that time, only chrome-plated G-bugle corps "competed' outdoors) we had an overlay (maroon "K" and some ornamentation) with epaulettes, white snap-on spats (with under-foot elastic), white gloves, and (again, white and maroon) hats.
As the coat and trousers were black (wool - which kept us warm in the bleachers) They ended up being nice concert "tuxedos" for most of our playing.
At regional and all-state events we were (at least, in my view) the only ones who weren't sitting up there in clown costumes - ie, bright versions of green, red, yellow, purple, blue, etc.)
Davids' and Carol's trousers were obviously not let out far enough (probably their Mom wasn't a seamstress) but mine fit nicely - as did those whose mothers sewed.
I'm guessing that their current ages are c. 70 and 74. Carol married the (recently deceased) amazing 36K sousaphone player (in our band, who I've mentioned to many times).
David (retired elementary school teacher - who grew weary of Memphis chaos) moved to a small town embedded in the Colorado Rockies, is a classical/folk/jazz/soul/eclectic DJ, lives above the station in rented rooms, and also (I'm thinking...??) works at a guitar store... https://spinitron.com/KVNF/dj/142199/Co ... vid?page=1 (Their family actually moved from Idaho to Memphis in the 1960's.)

bloke (football game version...a scan of one of those popular-for-a-few-years "fingerprint-proof" prints...thus the dots being picked up by the scanner) Note that a sousaphone wood case (though I was interrupted by my sister when sliding it in) fit in the trunk of the '71 Catalina. Yes...One trouser-leg was barely hiked up, but - that was me wrestling with the sousaphone case, and not my Mom's fault.
