The Chelsea boots - quite frankly they are to die for. Whether you would deem yourself a Chelsea boot kinda guy or not, these could be the boots to sway you. The quality is just insane, so much so I'm a little surprised at how cheap they are. But I won't mention it if you don't! The chinos are quite slim fitting and I think make a nice alternative to your bog standard navy. You'll definitely need a 38 waist in these. Make sure you open the link on the Sunspel shirt so you can see the zoomed in images, it has a really cool subtle check and the fabric is a thicker melange type. Amazing for a casual shirt to team with jeans. It's regular fitting so a size large should be spot on.
Another pair of boots to start with. The tan looks lovely with a mid wash denim - the Scotch jeans you'll want a 36 waist in. They're a straight fit and a little generous on the waist! This is the first time I've suggested anything from B.D. Baggies for you. The bradford fit in a size large should be perfect based on the items you've bought previously. Another one worth mentioning how amazing their fabrics are. I really like them for casual weekend staples, they're just easy and long lasting. The Nigel Hall knit is just a cool classic, whether you've bought something from him before or not. I definitely think the brand as a whole is right up your street.
Now for some smart trainers, they're from a really cool LA based brand called TCG. Definitely check out their website and you'll see what I mean! The Tommy jeans are a straight fit and for these I think you'll need a 38 waist. I know Scotch and Soda is one of your favourite brands, so I guess the jacket is a no brainer especially considering the price.
Make sure you check out the rest of the site, there's some ridiculous deals as you've seen so far and a few other bits I think you'll really like. But if there is something that takes your fancy, make sure you go for it ASAP as everything is in limited numbers.
