Just to add some info about the organization he was helping was called The Teen's Closet and it just opened recently. More info here, but below is an excerpt.
One such partnership is The Teens Closet, a place where disadvantaged and homeless teens or their parents will be able to pick out and try on donated clothing. Normally, teens receive a bag of clothing pre-sorted by other youth.
Students donate much of the clothes, partly because Ray visits classrooms to make them aware that so many of their peers are homeless.
“Teenagers of all ages have their own personality and own style they like to reflect,” said Ray, whose work has made her acutely aware of the challenges that homeless and low-income kids face. She understands that when kids feel comfortable in their clothes and are not teased for looking unkempt, they are more likely to stay in school.
