To start, I love this jacket. I was worried as you do with sizing, but it is spot on. Order a hair big to wear stuff under. The jacket is made for everyday use, so there will be things that aren't 'movie perfect' but honestly, no one will notice but you and the die-hardest of fans. If you want the real deal you know where to go and you have to pay for that! This is higher quality than any cosplay coat by miles, but is more affordable than the original. If you want a really amazing jacket, great fit, lovely feel, and so comfortable to wear then this is it!
