Another question i have is i’m working towards changing my casual dress,and dress casual attire.simple reason is because i was wearing supeerhero attires such as Batman because i’m a largely BATMAN COLLECTOR,AND FAN,AND I’M 46 YEARS OLD AFRICAN AMERICAN,AND A MINISTER OF THE GOSPEL.I’VE BEEN WEARING BATMAN T-SHIRTS,AND BATMAN BUCKES,BATMAN BASEBALL CAPS(EXEPT I WEAR THEM AT WORK BECAUSE OF THE STUDENTS),IN FACT I DO WEAR REAL BATMAN JEWERLY 14 GOLD RING THAT I WEAR EVERYDAY,AND A COUPLE NECKLACES.OVERALL!! SIR I DON’T WANT TO LOOK TOO MUCH LIKE A COLLEGE STUDENT,BUT A MIDDLE AGE MATURE MAN.ANTONIO TOLD ME TO LOOK LIKE BRUCE WAYNE,ALL HEADS WILL TURN. WHAT LEATHER BRIEFCASE BRANDS YOU SUGGEST?THANKS!!
