The brand is X2 - Seoul Collection, made in Korea. This shirt is effortless cool! It's a stunning blue with a mustard and black stripe through it and is in a soft, slightly slouchy material. Can be worn completely open and has a slightly batwing sleeve. Super easy to wear and it just looks great and flattering on.
