I havent started yet. I am watching you tube video of different stitches to see how it looks. I think on the top bit I would use a close stitch like half double (is that right) and then towards the bottom maybe double crochet with a chain in between or something like that to make it more open. Have to read your PM again, did you use DK or fingering weight for the shirt.
I may try to have a go at the shorts as well, was wondering if you could crochet with yarn and elastic together to make the waist elasticated or would you sew in an elastic after the crochet is done?
