Workwear; or, Dandy rigouts in which to perform manual labour.

Did the search and couldn't find a thread about workwear.

I presume there are plenty of people who work in manual labour(ish) jobs and as such are wearers of workwear. Tradespeople, craftspeople, technicians etc.

I work as a heating engineer so I spend my days building plantrooms, pipework and ductwork mostly.
I don't have to wear a specific uniform but I always struggle to find the balance with what to wear.
It can often be a fairly dirty job with plenty of opportunity to tear/ cut/ burn clothes so I've been tending to just wear jeans and a revolving carousel of Primark sweatshirts/hoodies which are basically a consumable.

I'm permanently on the lookout for snazzy workwear however so has anyone any top recommendations?

Not a huge fan of the shiny Snickers type of kit, I used to wear it all the time and while it's practical I just didn't get on with wearing it and the materials aren't terribly pleasant. The only Snickers trouser I actually likes were the floor layers ones which are super heavy cotton as opposed to the polyester type.

I'm also super keen to find a nice pair of safety toe boots that don't look terrible, something classic styled and comfortable for all day wear?
I'm currently wearing a pair of Equitector boots but I'm between sizes so they're not the best.
