How does the sizing run?

It runs small. The chart follows Asian sizing, which is about one to two sizes smaller than US and EU sizing. If you are between sizes, take the larger one.

Do I need something underneath it?

Usually yes. The hollowed-out pattern is open, so a camisole or tank underneath keeps it wearable outside the beach.

Cotton is the main fabric. There is no stated stretch content, so expect a firmer, less elastic fit than a jersey knit.

How should I wash it?

Cotton like this is best washed cold and laid flat or hung to dry to keep the open pattern from stretching out. Skip high heat.

Is it a blazer or a shirt?

It is a pullover shirt, not a tailored blazer. It has no lapels, lining or buttons, so treat it as a casual top.

Will the color match the photos?

Colors can look different across screens, so the actual shade may vary slightly from the images. The eight options range from white and black to pastels.
