I found this tuxedo style vest for $6 which, to me, is practically a fortune. It was a size 10 so I just wanted to take it in around the bust and the arms and leave the bottom as is for a flared effect.
Just a minor alteration today so it went from this...
All I did was open the arm holes at the bottom. So in case I messed up I could sew it back together and my arms would hide the imperfections.
Since the vest has lining, I folded the inside out to make adjustments to the seams.
