This vest is made so you don't have to wear a shirt (or even a bra) under it if you don't want to. Its cute, casual, low-cut, and lined. This is a pure crisp white linen. All our fabrics are upcycled deadstock. Dry-clean only if you want it to remain the same. You can wash it, and even dry it if you want it to shrink. It will get smaller, softer and lighter colored. We hope this helps you decide which fit is best for you. Feel free to email us with any additional questions.
