Alex Mill Double Button Back Shirt in Wide Stripe

Alex Mill has always cut its women's button-down shirts to men's size gradings—meaning you'll get a perfectly slouchy fit. In this button-down, available in crisp stripes and classic solids, you'll also find buttons along the back vent that open for an even more relaxed fit (and a hint of extra ventilation on the warmest days).

Early reviewers say this shirt is a must-have. According to one shopper, "Alex Mill really gets the oversized tunic type shirts down perfectly. I'm always looking for a blouse that is unfussy and looks cool the moment you put it on. This is that too. Simile to some of their earlier tunics, it's long and drapes just right."

AYR is one of BAZAAR editors' favorite basics brands, and its Deep End button-down is our favorite style in its lineup. It also made Oprah's Favorite Things last year.

On Amazon, you can find it in several bright shades for layering over a swimsuit or denim shorts. (And for even more detail, we have a detailed AYR shirt review dedicated to how this style lives up to the hype.)

The brand's cotton poplin is lighter than air, while its voluminous cut is made for wearing open over a swimsuit or buttoned up with jeans. Just don't forget the matching boxer shorts.
