The Victorian Era started officially in 1837 when Queen Victoria of England was crowned and took over as leader of world fashion, knocking the French off that pedestal.
That Early Era that took the Regency Fashion concepts of 1800-1828 and made the skirts bigger, the corsets tighter, and the bodice lower and longer, evolved through the 1840’s an 1850’s. Suddenly in the 1850’s the hoop or crinoline was designed by Parisian designers, and carried to Victoria by her buddy Eugenie – thus the French took over the fashion lead again.
