I know they are similar trim fit nappies, but I need to know the difference fit wise between a Large Bundle of Buns and a medium Itti Bitti? A friend wants a BOB but if it is the same fit as an IB she wants a wider crotch perhaps 1cm and a higher rise front and back 1-1.5cm on both.

Can anyone put a couple together and tell me how close in sizing they are.

TIA
