Hiccup!

hi I was wondering if you could help me I'm trying to make Astrid for next may at London comic con and my friend said he might go as hiccup but we are both really bad at making things so its going to be hard for us.

so I was wondering if you could help me with some questions
1) how did you make his black leather armour vest
2) what material did you use to make it
3) and also how long did it take for you to make it

and also how did you make his tunic I've never seen one this beautiful this great so beautiful and what material did you use for that as well.

I love your hiccup cosplay I think its amazing

many thanks charlotte xxxx
