Cascadas are great but I also have an issue with sizing. I'm 5'4" and a bit and size 8/10 so on the small side but not unusually so.
I have the women's xs which don't come in different lengths so I had to shorten them. The only way to do this is at the top of the leg, because of the side zip and ankle cuff. I think the resulting seam just below my bum makes me look like I'm wearing a nappy, fortunately it's not noticeable under my jacket.
The elasticated waist is too tight. so I snipped the elastic and use a belt.
They are not the most stylish trousers I own, but in wet weather they are definitely the most comfortable and practical.
I only wear them on very wet days when the rain has set in and doesn't look like stopping.
Powerstretch leggings are very comfortable, even in fairly heavy rain as they stay warm and only seem to get damp.
