In short - whatever you feel comfortable in. For some people that will be jeans and a t-shirt. For others, it will be their fanciest dress or suit. There is no mandatory dress code for Sinfonia events. If you do not feel comfortable or have the means to get dressed up you do not need to. If, however, you have the means and desire to dress up, please do! We would love to know that we are part of your special night out.
