I hate to say it.... but it's not the 65th anniversary... since they were worn a couple thousand years ago. There are ancient greek friezes as well as both greek, and minoan red and black figure potter depictions of them. Persia and the far east had them as well. Cold northern, and later any puritanical region didn't have them... although most places here in the US and Southern Europe in the past 200 people swam NAKED... but this Louis guy didn't invent them, he just popularized them. ((I absolutely HATE it when people publish articles with zero research put into them. It's just so IGNORANT))
I always thought bikinis on girls without breasts was kind of silly, but they work VERY practically on any little girl who isn't potty trained yet (for being able to change out swim diapers without having to strip them completely naked), and in our land-of-no-sun they're great for increasing vitamin D absorption.
For body-comfort, yes. I'd buy them for my toddler and allow my girl's to wear them. I never wore them growing up, because I did diving and surfing. Either case would have meant I was sans top or bottom several times a day.
