Boyfriend Button Up Shirt
Sea La Vie
A menswear-inspired pajama that’s ready for the light of day. While it’s the perfect partner for our Beddy-Bye Shorts, the Boyfriend Button Up Shirt doubles as a poolside cover-up or a polished layer over denim. With a tiny heart detail on the collar and embroidered motifs on the back—Sea La Vie or The Lucky One—this shirt is entirely too chic to stay under the covers.

The M runs large, wish the small was in stock... but its so cute, it's a keeper. I where it open with a tee underneath so it looks oversized. Great quality, even if a little pricey!
