Frank & Eileen Eileen Relaxed Button-Up Shirt in Acorn Brown Plaid

Eileen is one of Frank & Eileen's best sellers for a reason: a generous, circle-shaped cut with soft rounded shoulders and a shirttail hem long enough to stay tucked, built with the same bust-flattering button placement the brand made its name on. This Acorn Brown plaid version brings that fit to a pattern that works far beyond a typical flannel shirt.

It's a genuine three-way piece: layer it open over a tee, tie it at the waist over a dress, or wear it on its own with denim. That kind of versatility is what makes one well-made plaid shirt worth more than three trend pieces that only work one way.

Frank & Eileen applies the same shirting rigor here that built its reputation on button-downs, so the plaid holds its structure and the fit holds its flatter through regular wear, not just on the first try.
