I tend to wear dresses and the occasional skirt for work but now and again I'd like to wear a pair of trousers. Never used to be a problem but I've recently lost some weight and am now between a 14 and 16. The 16s I currently own and those I've tried on in shops literally fall down, but I can't find a pair of 14s that I can a/ do up or b/ breath in. 
Any suggestions?
