These are dress shirts and blouses. All are size 9. The shirt with the light blue tag is a thin, summer-weight fabric. The shirts with the white tags are made of a material that can be worn year-round. The white-tagged shirts have noticeable yellowing around the collar. It's less noticeable when worn, but they show considerable wear, so please refrain from purchasing if you are concerned. I have stored these without wearing them for several years. I'm listing them in case someone urgently needs them for job hunting, wants to use the buttons or parts of the fabric, or can fix the yellowing.
