I don't own any cycling clothes. Mostly I ride my bike wearing gym shorts and a t-shirt. I'm pretty fast, tho.
When I pass someone in a lycra bodysuit I'm like "lol get gud loser".
When I get passed by someone in a lycra bodysuit I'm like "chill bud, it's not the tour de france".
When I get passed by someone casually riding an ebike up hill at 20mph I'm like "REEEEEEEEEE".
