Oof. Posture to make an English schoolmarm shudder. But the suit fits nicely anyway.
The pattern is Jalie 2443. I chose the suit size according to her measurements with a little hesitation: size F (toddler 2) for width and size H (4) for girth/torso length. But the pattern is definitely true to size. Gracie's is a straight size F. They have the same waist measurement, hehe!
