The white shirt even has

its own icons. Old Hollywood stars such as Audrey Hepburn and Grace Kelly wore them loose with capri pants or tucked into pencil skirts. Another recognizable look comes from Julia Roberts in Pretty Woman, in which she wore a white shirt tied at the waist and a miniskirt.

Modern-day white-shirt muses, however, include the likes of Jenna Lyons, former creative director of J.Crew (after all, she reconfigured how we view this humble item). But perhaps our favorite go-to celebrity for white-shirt styling inspiration is Victoria Beckham, whose insouciant way of rolling up her sleeves has us wanting to do the same.

But whatever your preference, one thing's for certain: Finding the one that fits you is like finding the fashion holy grail. It needs to fit just right, and not gape at the chest or be so huge you look pregnant (unless you actually are, of course). It needs to weather a coffee spill (because it will happen), and it needs to be long-lasting because when you find the ultimate one, you'll never get rid of it.
