I completley agree, say no to the dresses. I have one from workign at a hospital and it is all kinda in proportion, except for the arms, i don't know who designs the dresses but they seem to think that someone who is a size 8 will have amazingly fat arms and needs huuuuuge sleeves, anyway i never wear it, the tunic is better.
I am surprised the uni's don't give you the option of wearing a dress though, i mean if you have massive arems it'd be great (joke). Once you actually go to work in a hopsital you will have a choice of tunic and pants or a dress, and even on some wards you can wear scrubs, which are personally my favourite, they are so comfy!
