Joji Locatelli is one of my favorite top-down designers. My latest Joji project is the Staple Linen Top, which is a go-to wardrobe staple - especially in Queen City Coleman, a gorgeous year-round blend of silk and linen.
The Staple Linen top looks great on a variety of body shapes and sizes, and is easily customizable, so you can add your own flourish. I narrowed the shoulders a bit, and shortened the armhole - all of which are pretty simple to do. Since it's worked top-down, you can easily change the overall length as well.
The finishing is up to you. Leave the edges plain, or add a quick edging. Take the neckline up to a turtleneck, if that's your jam. There are a million ways to make this garment your own, and I'm sure you'll want to knit several and try them all.
