Amazon Essentials Women's M 3/4 Sleeve Button Popover Shirt Navy White Petals. 100% viscose. V-neck with 4 buttons up front - buttons only go slightly down front, elastic at cuffs. Only worn once so no stains tears holes or signs of wear, however I just noticed small imperfection in the weave of the fabric on the front, it is hard to notice and is just a factory flaw, not wear.  See closeup. From a smoke-free environment.

Measurements:

22" across flat front of chest

26" in length from top of shoulder to bottom hem
