Hi Kaz! Sounds like you're a good candidate for beau coo (bloggers review here:
From the corners of the Curve.: BeauCoo: My new Social Media Addiction. )
you put your measurements in and you see people with a similar shape & what they wear- simple!
i had the same problem as soon as my size 26 clothes wouldn't stay on anymore, shopping on the high st seemed so daunting when I was used to one or two shops with a pretty limited selection.
I looked for for advice too & Magazines would say wear dark clothes that "skim" problem areas- flute that! I want to rock my bod now! I still have big legs but I couldn't give a flip, I wear dresses nonstop because that is what I like. Wear things that you like, be brave & confident- you'll look awesome in anything!
