Poor fit for certain "shapes"
I have 4 pairs of mens RR trousers and wanted to get my good lady some waterproofs. I ordered her a pair of Whispers in S & M as she wasn't sure what would fit.
The M's were too big in the waist but fine everywhere else. The S's were fine around the waist but way too tight around the bum and thighs.
Lovely as their trousers are, as with many manufactuers, they won't fit ladies who are slim on top (she's a UK 10), but who have slightly more "ample" bums and thighs. Back to the drawing board!
