For Christmas, I made four tees for some lovely young women in my life.
I started with four solid-coloured H&M classics. I cut them each with yin/yang fronts and diagonal back, then sewed opposites together.
I got the dimensions wrong for one young recipient, so I opened the seam and used the leftovers from a recouture I did for her mother to create a peplum hem and side-slash to widen the breadth.
