Here’s a doll soaker pattern that fits on the American Girl Bitty Twins 16” dolls, and some teddy bears. It’s knitted flat and then sewn together at the end. There are two versions. Version one (on the left) has simpler knitting instructions, but a crochet leg cuff is used at the end. Version two (on the right) has more increasing/decreasing, but no crochet is needed, other than the drawstring.
