Excellent service, knowledge and kind. I took my daughter in to get fitted for her first bra as well as a supportive sports bra. Kelly was exceptional at showing my daughter how a bra should fit and feel and what sports bra was needed. My daughter loves her bras and sports bras and we will be back as she develops and grows. Can’t thank Kelly enough.
