A friend recommended Simplicity 1513 which had a mix of separates for both knit and wovens.
I'd bought a pack of M&S knickers a year or two ago in the wrong size and it occurred to me I could use them for the doll. Fortunately the size was way too big for me so even more fabric in them. This basic T-shirt is in groups of garments marked as views A, D and F so I found it rather confusing separating out the correct pieces initially. Why they didn't give it a separate reference I've no idea!
I used one of my vintage Berninas but it's an early computerised model 1130 with no presser foot adjustment control and opening it up to adjust the presser inside as you can with earlier mechanical models isn't a great idea. I normally use a walking foot for knits (mostly spandex) but it's way to big and obscuring for tiny clothes. I tried the teflon foot which was an improvement but not as good as the walking foot. I managed.
First attempt.
The overall look was good (from the front) but the back armscye was stretched out in the process of turning under and stitching. Mental note to sew a stay stitch a hair away from the fold line next time and turn under with a delicate touch.
This crop top was view E and the cropped pants view D. Two of the knickers were in opposite colourways so I thought they'd work well with this. The little girl I'm sewing for has two of these dolls so I thought she might like dressing them alike but not exactly the same in this set. I could only fit the cropped version of the pants in the knicker fabric but I'm really glad as I think it's an ideal length for the activewear look. I did the stay stitch around the arms and went gently - that worked much better.
The first attempt resulted in a hardly there midriff gap and the pants did seem too deep in the rise. I made both sets together so the quick fix was to take in the joining seam of pants yoke and bottoms another 6mm. In the end I think the shallower depth of the contrast yoke actually looked more balanced with the crop top and there isn't a plain version in the pattern so I'll stick with that if/when I do another.
