Looking for a reasonably fitted (ie fitted shoulder, tailored/military style, not very oversized) woven cotton or linen jumpsuit in denim or navy, ideally long-sleeved and full-length. A tall version would be great (I'm a little long in the body) but may not be necessary. Some stretch is fine but ideally the fabric should be a good weight (like twill or denim).
Mainly I want the fit to be right (which I can only really tell by trying on) so happy to compromise on colour etc if it looks like it's worth a try. Shorter sleeves might be ok if legs were full-length or vice versa. I do want to avoid polyester and very drapey, silky, fine or clingy fabrics.
The photo is an NLST one I tried on and it was very close to the right thing but cropped, a bit too big on top and the dropped waist wasn't ideal.
Some other near-misses:
This is fun but cropped/short-sleeved (and black): www.freddiesofpinewood.co.uk/ladies/ladies-jeans/chain-gang
I love this style (I might buy one to try) but I suspect it's made of lightweight fabric (and again black): www.peopletree.co.uk/women/tamsin-playsuit
This one looks amazing on if you're petite. On me it was too short in the body and in a larger size the legs were very flappy. www.freddiesofpinewood.co.uk/ladies/ladies-jeans/grease-monkey
My budget is up to around £200.
