If you do want to wear it with a shirt, make it a stiff white dress shirt that's on the oversized side – size up on the knit, too – and skip the tie. Drake's did not invent the sweater vest, nor did it bless the world with the sleeveless cardigan, but if it came out tomorrow and told us that it did, we'd be the first to believe. Shirts, ties, sport coats and rugby shirts are all superlative at this Savile Row-based outfitter: feel free to add the sweater vest to that list.
