Theoretically I am a size 14/16, 5'8 and 34F but:
My torso is very long, and tops are always too short. The boobs and waists of dresses are always in the wrong place. (I have a custom build bike, when I was measured for it the framebuilder said my back length was more typical of someone 6' tall, I'm 5'8").
My calf muscles are very high and very chunky and pronounced. I can't get most trousers over them. I don't really want to wear bootcut trousers. I work on building sites and wear trousers a lot for tucking into wellies. There is one style from Next (sexy slim leg) which fits perfectly. They haven't made it for about 5 years and eBay supplies are running low. And I really ought to wear something smarter than jeans for work, even on a building site (I am project management rather than a labourer).
My feet are size 9 and wide. This limits shoe shopping massively. I'm sure that psychologically I wound up working in construction to limit my need for formal shoes.
I realise that there are specialist shops like LTS (poor quality) and Duo/Ted and Muffy (£££!!) and Clark's do some styles in a ladies wide fit 9 but I'd really like to wear trousers, and I'd really like to just go to a shop and have choice, and buy something that fits. And actually about 30% of my work time I'm in the office rather thdn on site - the dreaded "smart casual".
Was actually crying in frustration in Asda a couple of days ago trying on trousers that got stuck at the ankle (but I have had a similar experience with Toast, I'm hitting all price points here).
I have tried a Personal Shopper (JL) who was not that helpful. Ended up with a White Stuff tunic and leggings, which is really not me.
I've been slimmer (was briefly a 12) and larger (post pg 18) but my long torso, chunky calves and massive feet remain the same. I live in baggy jumpers, the afore mentioned jeans and Blundstone boots and feel like a freak. I own lots of running tights and long-ish coats because that's what fits!
