Victoria here, Beckham or Starmer, take your pick janejudge, you made me laugh! Maybe you thought it was me because I said I was wearing a green dress to a wedding yesterday, which I did with aplomb of course! (Photo provided, if you wish!)
Seriously, though, Dickens, is spot on. Fabrics do not hang the same on average size bodies with curves - be that ample busts, rotund tummies or large bottoms. The cloth will just cling and crease, unless you wear such a big size as to look like a tent. On a skinny tall frame the garment will show itself off to its best.
Dickens was not hung up at all on weight and fat.
