Floral blouse with lining

Floral blouse with liner tank. This was purchased from Nordstrom rack and is from the brand Daniel Rainn in a size 1X. It is flowy and I wore it as a true size 2X for work. There are some threads popping up by the buttons but is in good condition. The tank is attached to the blouse (see photos). Comes from smoke free/pet free home.
