SO funny, Hokiemum told me that our local TJMaxx had some Petit Bateau t-shirts for like $3. (If you've never heard of PB they're an older French company, high quality unders with a crazy high price to match, about $18 for a freakin' pair of *childrens* panties!)
So I went, didn't find any shirts - but OMG!!! I freaked out. In the 9-month old section of the Infant Wear there was this pair of knit pants. I look, I feel - They're WOOL and they are Petit Bateau!!! I couldn't believe it. I can't imagine what they normally cost but I only paid $12.99 - I can't even find any listings for them anywhere so I think they're uncommon, who knows...
SO get thee hence to TJ Maxx!!!
They're knit in garter stitch, they have seams, but they're quite nice with a high rise so they'll cover a diapered bum well. I don't think they have much shaping in the bum area, though. I think they'll work out pretty well for nighttime, they're fairly thick.
They'll never match the gorgeous WAHM handknits, but they're not bad at all!
