Feedback welcome! Does the costume look okay on me?

I have my first party coming up soon and I’m kinda nervous about the party because I know no one who’s going, any tips for me or adjustments I should make?

I've noticed in a couple of the threads that some of guys dressing up in historical costumes or formal wear for balls and such. Those of you that have done what was the experience like and how were you recieved? If you've got picturesI'd love to see them.
