This balloon-sleeve shirt from MACPHEE features blue and orange stripes. It had a vintage feel to begin with, but repeated wear and washing have caused it to fade from its original colors. The sleeves have elastic, creating a cute balloon shape when worn. The material is closest to that shown in the 7th image. There's a button at the back of the neck. As shown in the 4th image, the back is open. It's sexy and cute, even within a casual style. Thank you for looking.
