Because I thought it was a fairly shapeless/straight up and down sort of dress (ie no waist). Is this right?
As an hourglass, I usually rule out anything described as a "shift" dress but then again, I would probably suit this and this and this and this ... all of which are described as "shift" dresses.
I'm just a bit confused, I guess and having recently been doing a lot of internet shopping for dresses, I need to know what's what!
