I even loaned it to a very slim friend to try and she couldn't get it over her hips either. So now I use it as a display piece ( luckily one of my mannequins has no hips!) I think if it had a zip at the back or more shirred fabric it would have been ok. It must have been terribly disapointing for Cath Kidston. There are quite a few of these swimsuits on ebay at the moment.
However the good news is that this year she has got it right! This one is from her new summer catalogue and has just arrived here! It is made of cotton with shirred back and side panels and ruched front. The fabric is a beautiful grey and floral pattern and it has a decorative bow at the top. It is very similar to some vintage ones I have had in the past and it even stretches over my hips!!! The only improvement I think it could do with would be a little more bust support and perhaps an inner lining. Overall I think it is one of the nicest modern day swimsuits out there!
