What dress shape would suit me?

[Muchtoomuchtodo]

I’ve never been a huge dress fan but after a recent work trip I’ve realised that I probably ought to have a couple of casual ones for the summer. The trouble is there’s too much choice and I have no idea what style / shape would suit me.

Late 40’s
Fit but overweight (5’6” and 83kgs)
Quite broad shoujders
Smallish bust (B cup)
Large tummy (muffin top)

Help oh wise, stylish ones!

I find shirt dresses most flattering, they skim my tummy and can be tied to give a waist shape. I like plain or with a vertical pattern
