Help find the holy grail of skinny black trousers!!

[Shnorbitz]

I need a pair of black skinny trousers with an amount of stretch, that hold me in, look smart and make me slimmer wearing to work with longline tops and heels and only skinny looks 'right'.

I've tried ponte trousers but they're too much like leggings and I am now on a pair of Next trousers that were labelled 'smart' but the stitching down the front isn't doing it for me.

I'm also an 18 so not the easiest thing to find. I've been through the entire Next catalogue, Simply Be, Very, Matalan, Tesco and Sainsbos and still no joy

H&M for me for trousers always.

They have a nice amount of stretch in them and are comfy and smart.

I'm sorry, I'm useless at links, but the M&S ones are £19.99 and called Super Skinnies. They are recognisably trousers, not jeggings. They just don't have front pockets. I'm an hourglass shape, the poster above who's a size 10 and feels a tub in them might be an apple? The M&S Skinnies are also good, but more expensive - I guess because they do have front pockets!
