Allegra Open Circle Back Mesh Insert Sleeveless Leotard for Women by Audition Dancewear. This simply stylish leotard features a circle-back tank with mesh inserts. The Nylon Spandex we use for our dancewear is of very high quality with the perfect weight, and not at all "see through". Additionally, our leotards are lined with a second layer of Nylon Spandex for complete coverage in the front. On styles with a seam under the bust, only the bust portion is doubled. Styles with mesh or lace overlaying the bust are not doubled unless the base is a white or similarly light color. The accent fabrics we use are also of the highest quality. Made in USA.
