Back when the Brits were sailing around pointing cannons at people and being delightful they didn’t respect local culture and dialects enough to bother with a “tricky” word so replaced it with an easier version. Unfortunately due to that expansion and the proliferation of English as the most common trade language the English versions tend to stick.
Yeah they are common beach wear but a visiting a site for looking at women wearing them is not something most people would do at work so they are probably right.
