It's also popular to have a bit of scrunch at the bottom of trousers, though these tend to be with the slim, straight-style trouser. Be careful not to have too much gathering otherwise all you are doing is highlighting that you have short legs.
And as you suggest, some brands offer short-leg styles.
Check out Jeans West, which has a range catering for short and petite. You can buy only online, they're not available in-store.
Don't forget a heel - where and when you can, try wearing heels with your trousers. The hem length needs to be slightly longer when wearing heels. Heels offer a lovely visual leg-line, giving the appearance of longer legs.
Enjoy your new trousers.
