You'll need a worsted weight yarn for that gauge. Worsted weight yarns aren't all the same, some are thicker than others. You may need to use different size needles to make gauge. Whichever yarn you decide you want to use - I'd suggest buying one skein/ball/hank to play with and make sure you like it before investing in enough for the sweater. You can do some swatches and wash them as you'd expect to wash the sweater, block them, whatever you want to know what you're working with.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
