They might call it the 7 Year skirt because you can wear it for 7 years and it never goes out of style. Maybe it's got something to do with The 7 Year Itch? I would have said that it was because the style is so timeless you can wear it over the span of 7 years and not be off trend BUT we've carried this style for MORE than 7 years and it still stays relevant, stylish, and on point! Like a comfy pencil skirt married a swirly circle skirt and had a baby skirt that is absolutely perfect. In case it's not clear: we love this skirt.
