Just because your Con is over doesn't mean the cosplay has to be. You can add many things to your everyday wardrobe to keep the fun going.
Dress up in the colors of your particular character. For example, love Aquaman? Put some orange and green together with a nice seashell necklace or brooch to pay tribute.
Wanna have a little fun while still being serious at the office, put your red and black together and let your inner Harley Quinn have some fun.
This was my Con cosplay for a cross gender Bilbo but I'd be happy to wear it out anytime with a pair of sandals on my bare hobbit feet of course and leave the toy sword at home...
