Baby footie Pjs

I need to buy my almost 5m old baby new footie pjs! He’s 16lbs and I’m looking to buy 9m. But all baby boy clothing just seems so cheesy, or super cartoonish, I want something classic, maybe solid colors, soft. Any suggestions? I feel like I’m always buying the same stuff just bigger sizes since there isn’t as many options for boys like there is for girls!!
