As the a long-time mentor, volunteer, and Board member at Minds Matter of NYC, a charity organization, Diana's heart is in the right place - but her wardrobe is another story. Diana is a shopaholic who lacks direction in her style choices. Her mantra is "If it's on sale, I'll take it." Her closet is overflowing with clothes to the extent that she can never find anything. Tim and Gretta intervene and help Diana scale down her clothing misfits and teach her the hard lesson of less-is-more. Fashion help from: hairstylist Tabatha Coffey.
