Vogue 1297 is an excellent pattern for Apples. It looks fabulous in striped fabric, thanks to the giant pockets set at a slimming angle. It's also surprisingly easy to make, even when you're working with an older sewing machine like I do!
My first version of this dress was made with a substantial brick-red striped knit. It's not a scuba knit, but it is almost that substantial. I do think you could get away with a medium-weight knit. Anything too light might not skim over you as flatteringly (no surprise to most of us). The minor wubble in the front-facing pic is my not-very layerable shirt scrunching!
