From the catalog site:

Fashion from the era of Czars, Kings, and Kaisers! Inspired by the design of the classic, diagonal-front cavalry lancer’s uniform, these handsome, unisex court tunics feature button-closed bat-wing collars and deep, cufflink-closed cuffs in your choice of smooth (midnight-black) or brocade-finished (white) satin-finished fabric. Note the ornate, antiqued silver-finished buttons! 100% rayon. Dry clean. Made in USA. Colors: Black, White. Unisex Sizes (chest): S (40), M (42), L (44), XL (46), 1X (48 - 50). Length (back collar to tail): 34" - 37"

This would be a great base for my Imperial Marine dress uniform. Add a couple of medals, a maroon cummerbund/sash, the proper trousers and boots, and the maroon beret. Dress up the jacket with some subtle insignia (rank and regiment number on the collars) and I'm set!
