The shirt was too big; I made it smaller. I forgot to take a photograph before I cut my shirt, this is the during photo, after I'd tried it on for re-size:
Here's how I re-sized my shirt:
1. Turned shirt inside out, button up, and pin the shirt using safety pins where it would fit better.
2. Take off and mark a line with chalk where the safety pins were in place, take out safety pins then sew all the way down the chalk line - I didn't actually sew on the chalk line, I stitched about 1cm away from the chalk line.
3. Cut off the excess material, serged my seams together, and tried on for size (as seen in photo above in mirror)
It fit fine, but I found it a little boring, so, made some ruffles for the front of the shirt out of the two strips cut from the inside .. Yes I know readers, I too have jumped on the ruffle bandwagon, but ruffles are cute, aren't they?
