<p>I would think re: boots most likely shed want snow boots to wear outside and would change to her audition wear, including shoes, once inside. Our D wore simple nude heels for all of her auditions. But wear what looks best on you and makes you feel most comfortable. Re: coats - I agree, if you are wearing it with a dress you may want a dress length coat. If you are wearing pants you have more options. I don’t think brands matter - but since you asked - Our daughter opts for LL Bean duck boots and a quilted down vest or her north face fleece jacket or patagonia pullover most days in winter when being casual. But she also has a wool pea coat and a down ski jacket for really cold days. She also likes the wool knit headband ear Warmers when it’s really cold. </p>
