Honestly, the ushers ought to have at least relieved her of the Starbucks.
When I used to frequent an Orthodox parish (granted, it was hard-core-ROCOR) they used to have one-size-fits-all wraparound skirts and veils on loan to women (visitors, I guess) who came in not properly attired.
To me, it always made the women look more dignified, and...
...little girls, always seriously cute.
I remember Satuday outfits.
Summer outfits that consisted of a short sleeved buttoned shirt and matching shorts.
A matching wraparound skirt and triangle kerchief was included so one could stop at church for Confession on busy Saturdays.
