I washed it once. The fabric is thin and the sleeves are wide, so it's very cool to wear. It's not see-through. It's wrinkled, but it will become smooth and sleek after washing. The area under the bust has elastic and stretches. The front and back V-necks aren't so deep that you'll necessarily need an undershirt, but it might depend on your body type and how you feel. I think it can be worn by people who usually wear sizes M to XL. The design is the same front and back. Instant purchase is OK. I also sell mainly women's clothing, so I would be happy if you would take a look.
