Hello, me and a friend were thinking of doing something like picture related for a convention (if it's not going to be too cold or rainy).
I have never really done cosplay or anything like this before and have been to one convention.

My fitness is slightly above average, not as good as the guys in the picture (I'm going to be DK).
I don't have the time or dedication to make a suit and after searching most of the suits look bad so I feel that's out of the question.

I wanted to ask, are people going to make fun of me? Will it look like I am trying to show off my body?
I just really love Donkey Kong Country and want to do a costume for one of my favorite games with a good friend, but I am still quite self conscious also after starting to improve my body.

What paint should I use?

Is there anything else I should know if I am going to walk around shirtless in a convention?

Thank you.
