I have a long-torsoed, tall 3 yr old girlie. She measures at 18-24 mo size for chest and barely the 6-12 mo size hips and waist (waist 18.5", hips 19"). It seems that if you have a tall but skinny child you would obviously be buying smaller size and lengthening, but then would you need to lengthen armhole since she is long torsoed and so much older? And would you need to change the crotch depth because she is skinny but tall? Is the only way to tell by sewing a muslin EVERY time I try a new pattern or new size?
I consider myself an intermediate sewer - but I never learned about fitting. Any help would be so much appreciated! So many of you gals who have blogs and tutorials have been such a blessing and inspiration!!
