Armed with several size charts, I did my best to hopefully make clothes that will fit them and maybe have room to grow. The striped fabric is a knit that was quite uneven and was difficult to make and align the stripes.
The little girl's outfit is made of a knit fabric that looks like denim but is more comfortable because it stretches. I really liked this fabric: it keeps its shape and looks like it won't show dirt too easily.
