Here is my 99 cent thrift shop extra large ladies shirt. I bought this while looking for shirts to debone and make into quilts. It is pink and purple seersucker...and pretty ugly at that!
So...what to do with this ugly thing? Remodel it, of course.
I cut off the sleeves, close to the armhole seams. There were buttons and tabs on the sleeves, so that the wearer could roll them up and button up the tab. I cut off the tab, but left the button on.
Next, I cut off the collar and took the shirt apart at all the seams. I picked out the pocket and put it aside...I had not decided at that time what to do with it. With matching thread and the shirt buttoned, I sewed down the front placket (the strip on the front of the shirt with the buttons and buttonholes) on both sides.
I pinned and cut out all the pattern pieces from the shirt pieces, replaced the front pocket on the front of the dress, and sewed the dress according to the pattern instructions.
And now, my granddaughter has a new (old) dress. I hope she likes it.
