You should check out the Pattern books at your local craft/ fabric store. I believe it's Simplicity that has some GOT costumes. Both Hobby Lobby and JoAnns will run these patterns on sale for $1 or 2 every couple weeks. This is a huge savings as most of the costumes run about $20. The tutorial was great, however as a novice you will find having the pattern will make this task so much easier. Also mentioned in the tutorial was the suggestion to make the pieces using a cheap muslin to try out size. I always do this when working with expensive materials or making a garment that needs to be fitted.
