Ooh that looks really nice. I’ve had to bookmark that stuff. I see Lamazi also sells it. I know what will happen, I’ll leave it till later and it will all be sold out in all colours!
Anyway, the pattern is designed for a much less stretchier knit so something to bear in mind. I would think it might drop a bit too as it stretches lengthwise too. If you’re planning on putting in the side slits it might be an idea to stabilise the area first. But I think it will be lovely in that! Look forward to seeing it. My fave colour!
