Yes I am a stocky guy, I always struggle with getting jackets that fit due to being 5'10'' but very broad. I figured that 2 buttons would be better for my height buy will try some 3 button and see how they look.
I live in rural southern scotland so access to shops and tailors are somewhat limited. On the other hand 6 of the maybe 20 shops in the village are woollen mills that selo Harris Tweed and cashmere.
Hey there, I would guess that you are probably near a Marks & Spencers? That would be a good place to start to get an inexpensive but well made suit. Once you've chosen your fit and style, and it fits well on the shoulders and is long enough, take it to a local tailor and get him / her to adjust the jacket and the pants as normal. M&S is good as they always carry a full range of sizes and you can mix and match the trousers.
I would go for a plain navy suit from the Sartorial range.
Then, get yourself some plain light blue and white shirts, no stripe, no check, just plain. TM Lewin would be again a good starting point for inexpensive yet durable and well made products (you can move on to your bespoke Italian shirts that cost €700 at a later stage!)
Then, get yourself some "classic" looking ties, rep stripe, solid colours, or lightly patterned (like a pin dot or small floral design). Avoid large patterned, shiny ties. If you want something fancier, you can trawl e-bay for second hand ties, either designer or handmade. I'd recommend Luxeswap on ebay.
White linen PS is the best starting point; or a lightly coloured / designed paisley to set off your tie / shirt combo. Not sure where you'd get these in rural Scotland, but I imagine there'll be some store within reach that will sell something like them (John Lewis)?
You'll get there. But have a look around here; look at what people are posting, and see the difference - its all about texture, and quality of the product, the balance of colours, the coherence of the fit, and the cut of the fit itself... I learned that too, and have changed my buying / dressing styles for the most part, for the better. See fits you like and ask, "why do I like that?" Try and analyse it and then apply that to your own combos.
