As the 2nd decade of the 19th century progressed…

…into the 1820’s, the emphasis changed from the 18th century rigid shaped body and the Regency flowing natural body to a silhouette with a small waist that had big curvy lines flowing out from it above and below.  The use of bust and hip gussets assisted the flowing shape of the curvy body being emphasized.
