Hey there!
Great costume idea...but i'll say, you'll have a pretty funny day wearing that
(talk from experience).
You shouldnt stop trying..you'll only get better if you step on it and try : )
You'll probably save a lot of time and money as well at some point...and such a great victory, finally doing it with your own hand!!
(yes yes..i'm a bit puritist in here..i know i know..sorry bou't that)...
You're beautifu! you'll definitly fit!!
I'm not quite helpful in here i gess, but if you need any help on particular parts, i can still try to give avice on the very very few i know^^"
