I get so jealous of all the cute things for girls also! But luckily I found YT..there are so many talented people on here that can make you just about anything you imagine for your little guy.
For PJs I definately reccomend
http://go.fetch.home.comcast.net/. She also makes cute fleece pullovers that come in a variety of boy colors/patterns. You definately have to try her night shirts for the boys as well... Mr. Biggs loves his camo one!
If you're looking for shirts plain or with sayings, then I recomend
www.barkindogclothes.com. Rena makes the most adorable shirts! She does custom work as well, so if you don't see something you like on her site, then send her an email and she'll work with your ideas. She also make cute tracksuits...But make sure you give her your dog's exact measurments, so she makes the arms and legs long enough for your pup.
Also, if you go to the featured seller's section of this forum, you'll find a whole list of people on here that make and sell dog clothing...and most are starting to branch out and make more things for our boys!
If you're looking for accessories, I also make blankets, beds, pillows, carseat pads, and toys

So I'd be happy to work with you on somme gifts for your little one.
