Nicely done, it's good to have a pattern that you know you can go to.
The only 'label' my DH will buy is George from Asda so I took it upon myself to make him a shirt last year - even he commented that the fabric felt lovely to wear. So, I've got a couple more lengths of fabric to make some more as I rather like shirtmaking.
I've found Croft Mill good for Italian shirting fabric.
