Interview tomorrow! Help!!!

I have a job interview tomorrow at 10 at a hospital for a registered nurse position. I've been a nurse 3 years in long term care and I'm trying to transition to acute care. I have no idea what to wear. I don't have a pants suit but I have dress pants. There's snow on the ground here in Massachusetts so I was thinking of wearing my nursing clogs as opposed to heels. Would that be bad? Also I feel like I'm getting sick. Suggestions???
