Help! I have an interview and don't know what to wear!!

[eyestightshut]

Have just found out I have an interview on Tuesday. It's for a Junior sister post (NHS). I wear a uniform for work, so don't have that suit/dress kind of smart work wear. To make matters more exciting, I am in work tomorrow-Saturday and have got DC to contend with as well, so a quick trip round the shops on Sunday is out of the question as DH is at work.
Am 5'5 size 12 with dark hair/pale skin.Would something like this be suitable? Also what shoes/accessories would go?
All suggestions greatly appreciated

I'm afraid I don't have experience of nhs interviews so I'm not sure what they'd expect you to turn up in but fwiw I love that dress!
