All 3 are in used, very good condition. They're cotton with a good amount of stretch. The long sleeved shirt doesn't have a brand name on the tag, but is size small. It's super comfortable, accommodating, and amazing for nursing. The short sleeved shirt is a very supportive wrap front nursing shirt from Old Navy. It's an extra small. The tank top is a nursing tank from The Gap (xs), but also works great as a maternity tank. Fits more like a small!
