I am pg and have put weight on massively everywhere 
but, did fit into a dress today which looked good apart from seeing hideous lumpy arse through the fabric. So need some control/smoothing pants but obviously not stomach holding in ones, tops of legs not too bad so could be shorts or 'full' pants. Have seen the spanx maternity things with hole cut out for belly but don't know if I'd be too hot as they come quite high up & are longish in the leg. Any ideas? Just need to smooth out arse craters!
