This is a fantastic site for tall girls!

I work for a company called Long Tall Sally (http://www.longtallsally.com)and we specialise in clothing and footwear for tall women, so I can totally sympathise with the issue. We have a wide range of smart and casual wear in sizes 8-22, trousers fit a 38″ leg and our tops are designed with longer sleeve lengths.

Working for a specialist tall retailer, I’ve also come across a couple of websites which have links to lots of resources for tall women (and larger shoe sizes):

http://www.extratall.co.uk,
http://tallorder.typepad.com/home/,
http://www.uniquelywoman.co.uk,
http://www.tallclothingmall.com,
http://www.heightsite.com.

I hope this helps in your quest to find longer inseams!

Alice, Long Tall Sally.
