Michael Kors Grommet Blouse v-neck long sleeves lightweight

Chiffon purple blouse with v-neck and grommet collar accents, long sleeve. Photos look blue on some monitors, but it is a purple color. I am a petite medium or large with DD bra and I can wear this Blouse.. see photo where I am wearing it with no pull or tug. It is tagged as XS, but it must be a mistake. It is 18" across, so I changed the listing to petite medium. 26" drop from shoulder to hem. Nice arm coverage and still a cute casual style for date night to running errands in jeans or shorts.
