I like stripey tops. Photo taken on boat to Brittany; coals to Newcastle next stop.
Stripey tops have been part of the (U.S. primarily) biker scene since the 1940s at least. I guess from the prison uniform to start with (
Auburn system - Wikipedia).
Lee Marvin wore one in The Wild One (basically the blueprint for 'outlaw biker' fashion). I think he looks cooler than Brando with his magic cap and his zipped to the neck leather.
Marvin based his character's look on Wino Willie Forkner, ex WWII serviceman and founder of the Boozefighters motorcycle club in 1946,
ABOUT — BOOZEFIGHTERS MC.
At The Hollister Riot in 1947 (on which The Wild One was loosely based
Hollister Riot - One Percenter Bikers):
Forkner wore stripes as he was a racer for the Yellowjackets MC (
https://theyellowjacketsmc.com/history-1) so there's a prison stripe vs racing club split - prison stripes are all the way across; racing stripes just the arms.
Photo taken in 1968 showing Terry the Tramp (Oakland HAMC) kneeling to the right (arm on mc wheel). Standing behind him is original San Francisco chapter president Frank Sadilek apparently wearing Lee Marvin's striped jersey from 1953's The Wild One. It doesn't look the same to me though so either someone fibbed or Marvin had more than one jumper.
Now that there's a newish wave of middle class 'moto culture' (eg
Bike Shed Motorcycle Club | Dining, Barbers & Motorcycle Clothing), stripey tops based on the above are all over the 'scene'; called prison stripes...
The above possibly comes via Japan though; Japanese skaters/bikers took loads of inspiration from 40s/50s/60s US biker styles and made them incredibly cool and detailed. A guy called Go Takamine is a big name on the scene in Japan and 'invented' Brat Style (

BIKE FOR SALE | BRATSTYLE-ブラットスタイルBRATSTYLE-ブラットスタイル), stripes were/are a big part of that in the early-mid 2000s.
Though that might also be inspired by Jack Nicholson in 1970's The Rebel (T)Rousers:
