Worn a few times. The chest has elastic, giving it a relaxed feel. (This is my personal opinion, for reference only.) The sleeves are not tight, and I think it's generally loose-fitting. Polka dot pattern. How about it for the lingering summer heat? Size: Length: Approximately 53cm Width: 45cm Sleeve length: Approximately 25cm Fabric: 100% Polyester The size isn't clearly stated, so I've listed it as free size. Please understand.
