Basic John Smedley v-necks and cardigans are on sale for 60% off right now at StyleGun. Once you discount for European taxes, that puts the v-necks at about $93 and cardigans at $110. Expensive, but these really are very well-made knits. I bought my first John Smedley sweater about seventeen years ago, and it’s held its shape and color beautifully. You can’t say that about many other brands out there. Colors right now include your basic navy, grey, and browns, which don’t go on sale at John Smedley’s website (they only discount seasonal colors).
The v-neck model on sale is their Bobby, which has somewhat of a small v-neck opening, making the neckline a bit higher. I personally favor this style, but some like the more traditional, lower neckline. It’s designed to wear a bit fitted so that you can wear underneath a sport coat. You can find measurements for it on Mr. Porter’s site, under their “size & fit” tab.
The cardigan is their Bryn model, which is also quite fitted. Unfortunately, Mr. Porter doesn’t have measurements for that, but I would take whatever size you’re in for the Bryn as you would for the Bobby.
