Go as a Revolutionary this Halloween

From the seller:

Astounding antique Edwardian or 1920s three piece, colonial style outfit. Dating from the mid 1910s to the early 20s, this three piece outfit was most likely intended for a child, but is large enough to be comfortably worn by a petite woman. In a colonial style, not unlike the outfits worn by George Washington in popular depictions, this was probably made as a costume for theater or for wear on a patriotic holiday or celebration. The make and composition is so stunning it could easily work in a variety of contemporary settings.
All three pieces are composed of a soft cotton in a sky blue "real fast color" dye. The lapels, cuffs and collar of the jacket are finished in two lines of yellow silk, as are the borders on the three tails. The decorative, non-functional, pockets are bordered in the same yellow silk. Cuffs are finished in a delicate, ornate floral lace with scalloped border.
Accompanying waistcoat is of the same light blue cotton with white cotton linen lining and back. Ornamental pockets at front finished in yellow silk double border trim. Secures down front with series of metal hook and eye closures. Decorative opalescent white buttons down front.
Matching pants are again of same light blue cotton. Openings at either side of waist secure with metal hook and eye closures. White opalescent buttons inside waistband allow for attaching suspenders. Bottom of pant legs secure with metal push buttons, and adjustable buckle at bottom. Buckle is stamped "ADJUSTA" and "Pat. 1-27-14 Pat's Pend". Red stamp inside pant leg reads "Regal Fast Color".
All three pieces in great, wearable condition. Some wear and tear as expected-- some areas of slight discoloration. Please see photos for condition and details and message with any questions.

From Me:

The buckles do appear to be from 1914. The big clue as to when this was made is actually the "Regal Fast Colors". I've found newspaper ads for regal going back to the 1930's but no earlier. That this is from the 1930's isn't too surprising.
