Make my own cosplay costume

so I decided just to make the vest again by myself. In 3 days, it actually turned out pretty good and I ended up still sewing the vest on my way to the con. BUT when I get there..well it was my first time being to an anime convention or anything like that..anyways there were so many people and I chickened out and didnt wear it!

Ive been trying to put together a cosplay of Luneth from final fantasy III for the past few months. Its not going very well, the most important part (the vest) turned out soo shitty. & the Convention is next week..arg, dam this!
