Being a mother, I would been happy seeing a young women who was dressed in a T-shirt and tights. Her hair was tangled.  I have one just like her!  She was never interested in clothing or combing her hair.
However her picture was hung on school's front reception hall as a top student.  She had many devoted friends around her.  Young people are beautiful like sparkling diamonds however they are dressed!

I could imagine the excitement of our Lord seeing them in the church worshipping Him!!!  :-)
