It's a bit early, but here's a pair of fleece-lined pajamas I bought at Nishimatsuya. The size is 90cm. They're plain with no pattern, so they're pajamas, but I used to dress my child in them separately for daycare. Both the top and bottom are fleece-lined, so they're warm even in mid-winter. They show some signs of wear, but there are no stains, so they can still be used.
