This button up shirt fits too small for me after having a baby, so I bought the exact same shirt one size larger. That’s how great this shirt is. I couldn’t live without it! The checks are a little smaller than a buffalo check, but bigger than gingham, so it works in any season! The material is really thin, so it’s perfect for warm weather with the sleeves rolled up or tied at the waist for a cropped look. And in the winter it’s great for layering under sweaters and vests.
