Unisex is disappointing. I wore 1980's j-cloths as a student and unisex scrubs are even less flattering and comfortable than those. And I say that as someone who campaigned to be able to wear trousers.
I'm female with hips and breasts. My scrub tops are square and shapeless. I normally wear size 8-10 on tops but need a medium scrub top to be wide enough for my hips. There are no bust darts or waist definition, and the shoulders sit somewhere near my elbows.
I also need medium trousers to get the elasticated waist over my hips. They are then too long from waist to crotch. I can choose between turning them over at the top, imitating a Michelin tyre or leaving them long and letting the crotch seams cause friction burns on my inner thighs.
The NHS employs hundreds of thousands of nurses. Was it really to hard to find uniforms that would be comfortable for female staff?
