There are people who makes it look great if they are cosplaying the same gender as themselves and equally great when cosplaying an opposite gender.
Take it from the famous Japanese Cosplayer, Furumiya Sui. She’s been in the cosplay industry for roughly 7 years, making her own costumes and sometimes borrowing from her friends. Although her costumes are not professionally-made, it is not that obvious when the pictures are already taken.
I’ve included her pictures in this post both as a male and female character and you’ll be the judge which one she cosplays best!
