Hello from Bidford on Avon

[Iminei]

The Pattern (McCalls 6044) called for a large but it did turn out a bit baggy(don't know why I didn't realize this when trying on the test shirt).

That is the devilry of garment fabrics!! You know where you are with a good 100% quilting cotton ...

I once tried to make some pedal pushers ... yes really ... and I made a toile pair out of some sort of faux denim fabric which fitted fine ... I then set out to make the pair proper out of a stretchy gingham fabric  ... before adding the waistband i tried them on ... and stood there as they slithered straight off me to puddle around my ankles!!!

Exact same pattern, cut and stitched the same as the well fitting toile ... but the devilry of a different fabric!

Well that was a very pleasant rabbit hole I've just fallen down @EdTheMaker.

There are some very nice fabrics on there. I may just have to copy your shirt for my DH.  Don't worry we are a long way from Bidford on Avon.

For everybody else this is a site I've never encountered before but looks good.
