Mom I loved my scrubs when I was seconded to NICU to gain some experience in caring for drug dependant infants back in the day. I kind of ended up w/ a pair and wore them as slob wear at home for years. Trouble is I looked like a bad Richard Prince living art installation. 
Good advice about what to wear to not get people's backs up. I used to get snarky comments from some staff when I attended W/R about 'affording' what I wore on a nurses salary. I'm a smart shopper, that's all.
Dry When DH was nurse/manager of the Dementia unit they brought in a uniform of polo shirt and chino's. He hated it because it actually made many of the patients more confused because they had become accustomed to each staff members individual look. The shirt was polyester so he bought some cotton ones, cut out the stitched logo from the poly one and sewed it on the new one. He always felt that the head of the unit should wear a different colour (like a modern matron would on a medical/surgical unit) to make them identifiable. Now he swings between covered in dust and dirt on site and suited up for meetings and client stuff! My washing machine always has lumos of cement, old screws and washers, pencil stubs etc clanking about in it no matter how I pocket empty.
My dress 'code' is no unnecessary flesh, no cleavage or thighs for appropriateness and safety, no obvious denim (although dark indigo can be got away w/), no clumpy DM's, no neck jewellery on DV's. It kind of relies on common sense but we do have to sometimes make it explicit w/ student nurses who get all excited at wearing MUFTI and dress inappropriately. My on call wear is a little more buttoned up and I always wear trousers on call outs as have, in the past, had to get some very reluctant clients into hospital and it can get a bit.....Having seen one staff nurse grappling on the floor w/ an agitated patient w/ her wrap skirt open to the waist and underwear on full display I am very careful now. (I managed to get close enough to cover her up.)
