I have just constructed the sketchbook shirt in size 12 and it is very short. I had a look back at the Oliver+s blog and noticed the back finished longer than the sleeves, however, on mine, the sleeves are a lot longer. I have checked my pattern several times and the back pattern does seem short. Is it just me? The pattern is gorgeous, and the shorts fit perfectly. It will not stop me making it again, I love it, but I will have to lengthen it by at least 4 inches.(The shoulders fit beautifully).
