Find that bootcut is flattering for us petites. Buy my clothes online from Very, which does a really good petite range. Have only ever bought 1 pair of trousers and 1 dress from M&S, because normally positively loathe their styles and wouldn't ever use them, but happened to get a voucher for £200 which felt obliged to use.
Have you tried Next or Boden Ana? I'm tall and their trousers are a good length for me. I also got a pair of skinny jeans from East in the sale for £13.99 which have been great.
I think as long as the top I'm wearing is suitable for the occasion then the style of black trouser is what you are most comfortable with. I like either straight leg or skinny trousers with ankle boots.
I used to rely on M&S for their slim bootcut trousers, but now they only have two choices and never in my size. I bought straignt leg ones last time but I don't really like them. Not many other stores do the long length I need.
I have just bought some of their soft, pull on trousers, which are less clingy than leggings, but still quite clingy. They look good under tunics with ankle boots. What surprised me was the £16. price, a bargain! I hope they wash well!
I am looking for a pair of smart black trousers but I'm confused by the styles - straight leg, slim, tapered. I have sent for several on line (M & S) but can't find any that fit. I am a short 10 but find so many look like jodhpurs or cling to the leg. Which style do you prefer for 'going out'?
