Does this shirt dress run true to size?

It runs small. The sizing follows Asian charts, which are one to two sizes below US and EU sizing, so size up if you are between sizes and check the size chart before ordering.

Is it a dress or a shirt?

It is a long button-front shirt styled as a dress. Worn closed it works as a dress; worn open over a tee and jeans it works as a light cardigan-style layer.

Is polyester a good fabric for this dress?

It resists wrinkles and keeps its shape, which makes it low maintenance. It breathes less than cotton or linen, so it can feel warm in hot, humid weather.

Will the color match the photos?

Colors can look slightly different from screen to screen, so the actual shade may vary a little from the images. The stripe pattern itself is consistent.

How should I care for it?

Machine wash cold on a gentle cycle and hang or line dry to protect the shape and the stripe print. Avoid high heat, which can shrink or glaze polyester.
