Some shapes are regulars for the Dress's ebony-and-silver style. Others, not so much. The "21" Zulu falls under the not-so-much category: we've only ever seen four in the Dress, this one included. Why that is I couldn't say, given that the Dress's dapper nature and the Zulu's balance of dynamic stance and languid lines really do pair wonderfully together.
