I have a Canterelli that I bought for summer wear its a super 110 a couple of years ago, its a grey with a chalk blue stripe, work wise I get a lot of wear out of it. As your a tradie and don't wear a suit all that often I would go a grey suit there a lot more versatile for social occasions and I have noticed that even cultural creatives are no longer wearing black suits all the time. Another option could be a price of wales check now that always looks good in my opinion and is never out of place at any social situation. As for shirts you could try http://www.harvieandhudson.com/ or http://www.hilditchandkey.co.uk/Gentlemen/Shirts/Button-Cuff/Default.aspx both are pretty quick in terms of delivery. I find for me that Herringbone i can never get a good fit there too tight across the chest or long in the sleeves for me.
