I purchase my sons shoes a whole size too big.  He had a Jury (performance in front of music teachers) on March 21, 2018 at The People Music School in Chicago.  He had to wear proper attire and dress shoes during his performance. As I was figuring out what he was going to wear I realized the shoes were never worn.  He dressed up for his performance and put on his new shoes and they fitted perfect.  I was so happy and he looked very handsome.
