The Eileen button-up is Frank & Eileen's best-selling button-up. I can see why. It has a relaxed fit you can wear every day. Plus, it's available in many plaids and solids. I think it runs big; I'm wearing an XXS. The top I'm wearing is Italian flannel, which is so soft and warm. I love the style, fit and the casual vibe. I also love wearing the Kane hoodie! It's a relaxed fit, and the style is perfect to wear as is or under a jacket. It fits tts. I'm wearing a small. @frankandeileen frankandeileenpartner wearloverepeat LTKHoliday LTKSeasonal LTKOver40
