Paul Smith

The sleeve and body will be balloon-like-put on the shirt inside out and get someone to pin in at the side seam in order to take enough off the chest and from the bicep area on the underarm sleeve seam so that you can still move in it but it is closer to your own body shape. Make sure you nip about 1cm more out of the waist to make a good shape. Take off the Paul Smith T-Shirts and lie it flat,then mark lightly (with a pencil or chalk) a new seam line where the pins are, then take out the pins. Remember, the cuff will be an OK size, so start sewing your new seam 2cm above it, leaving the cuff width alone. After you have sewn it cut away the leftover fabric 1cm from the stitch line.

Your Paul Smith Musa Trainer is now slim, but to make it fit even better, add two darts to the back (as marked on the shirt pattern online). Make sure you get someone to pin them out, then fold a line from the top to the bottom of the dart。
