I am a size 16 on my bottom half and, whilst my tummy is not that bad, I do have an overhang after 2 c-sections so I like knickers that are quite high up and I can tuck my tummy into 
I have always worn thongs for this reason but quite fancy some shorts-type knickers as they look a bit more classy - however, I am concerned that they will just sit under my overhang and exaggerate/not contain it.
As I can't really go and try knickers on, what do those of you who are a size 16 wear?
