My advice would be to go with slim cut jeans they are generally a safer bet and are just more suitable for people with larger legs,
I'm male so I won't claim to know much about womens clothes! but out of all my slim cut jeans I prefer my Versace pair as they are a very good cut.
However if you really want to have skinny I would ry Diesel they tend to have a bit more give in them than other brands (from the male range's I have anyway)
UK site but have a look
