In this scene from Did You Hear About the Morgans?, Meryl happily embraces her new Wyoming home. She fits in with the locals in a proper cowboy hat, still looking sophisticated in a sweet navy eyelet dress and soft pink cardigan. A pair of cowboy boots only seems appropriate, so be sure to shop these ones now, along with other items!
