yeah , it sounds totally appropriate , but add a few extra touches to let them know you care about your appearence , because if you just wear a boring outfit , you know in the back of their minds , that will keep with them . & go with flats , instead of pointy-toed shoes , but make sure the flats are also more professional looking & not too casual .
& i know it might be hot , but do you have a long-sleeved one , i know that makes it look a little more business-like .
hope i helped ?
