Hello all! :3 I recently purchased a MeyRin [Black Butler] cosplay from Amazon, and absolutely love it. It fits beautifully except
for the sleeves. I don't have "fat" arms exactly, but they are a bit larger than the social norms. I do have a decent amount of muscle too. But the sleeves are so tight that I can't even move my arms to put on the apron or button the dress! Are there any tips on loosening the sleeves so I can move? I have about 1/2" of a hem on the inside, and I've even considered putting in an extra panel to help. I am working on having a seam stress look at it in a week or so, but I was wondering if you all had some tips. :]
Thanks so much!
