First Job Interview

I have my first job interview..... It's for a Chiropractor's office. I applied for the receptionist/assistant job. If I land the job - I will be the receptionist and help with patient x-ray's as well - and billing. Brielle also has her preschool graduation today - kind of ironic they landed on the same day - but I am ready - I think. Now....what to wear? I have mommy clothes - not work clothes - good excuse to go shopping!! Wish me luck!!
