<p>Some of it depends on the tradition of the school. Generally, if a singer is performing with orchestra, long gown is de rigueur. Usually for an evening recital or gala event a long gown would be expected. Daytime recitals…if it is a culminating degree recital, maybe, but if it is an appearance on recital hour or divisional recital, a long gown is not expected or necessary, IMHO. A long gown is not appropriate in most audition situations…the exception might be something like regional finals of MET auditions, where an audience has gathered and are part of the occasion. A singer needs a good black dress, one which can be worn on the stage, and it should not be too short. </p>
<p>Addressing the issue of what a performer reveals: nothing should be a distraction from the music, the art. You show the legs, and the audience is noticing the legs; show cleavage, and we wait for the bow. If a dress is not full length and the legs show, the color of them should not distract, best to have a neutral color, or an “almost black” with black dresses. Bare arms are OK if they look like Michele Obama’s, otherwise, not a good idea. Flesh revealed is a distraction whether attractive or not, and then the issue of judgment and taste enters the mind and takes away from the performance. </p>
<p>If a female singer has black pants which fit well, are not skin tight and/or clingy, and the top is complimentary, that is fine for an audition or class presentation (especially mezzos who might want to be considered for pants roles…part of the audition…can you look the part?) </p>
<p>Do ask the choral director what the attire is for the various ensembles and plan for that. Some use robes, some expect everyone to find/use/buy/make a dress from an exact pattern and material, some do different concerts during the year differently. Almost all will call for a black dress at some point, usually a long one (it can be a long skirt and black top). </p>
<p>Shoes: dress shoes should should not be too high, tiny heeled, and/or backless. Hours may be spent on risers in dress rehearsals. Stage shoes such as character shoes are always needed and useful.</p>
