Convertible dresses (also called "infinity dresses") seem like an awesome idea in theory: You can wear them so many ways! They're relatively cheap! Everyone with a different body type can be accommodated! Except in practice, it's not the case, and you're almost always better off springing for regular dresses in different cuts but the same length, color and fabric from an actual store. It's almost impossible to wear a bra with most of the infinity styles, the fabric moves in weird places it shouldn't, it looks as cheap as it is, and they're hard to actually get into the style you want and keep it there. When I was forced to wear one, the only thing I was able to fashion mine into was a noose, and it looked better than any of the stupid options listed.
