cosplayers i need help!!

hey gang! i have a question. im going to a convention in march for 3 days, and i have cosplays picked out for the first two days. the third day, i have a few options, but- id love to go as octavia goetia. the thing is, i'd be 14 at the time of the con. octavia is from helluva boss, which is an adult show, so i'd only consider octavia because she is 17. she's still from an adult show. i'll be meeting many VAs from both hazbin and helluva, and it would be really cool to go as octavia. id be wearing clear indication of my age. would it be appropriate for a 14-year-old with clear indication that they're a minor to cosplay a minor character from an adult show?
