Eeyew. No. You are just a little bit away from being "that guy" in the bar who is 30 years older than everyone else, macking on the women with your shirt unbuttoned and your astrology medallion peeking out of chest carpeting. Don't be that guy. Fix it now while you can.
It isn't about what you look like. Who cares if you wear plaid with stripes? The rude part is forcing someone next to you to deal with being pressed by naked flesh for hours on end. Cargo shorts are fine, but cover up the hairy pasty parts that might touch other people. Consider this a public service announcement.
