Empress Eugénie's basque-waisted wedding dress was the subject of many prints, including this one. There are often two weddings, one civil and the other religious. This would account for why she seems to be depicted wearing two different wedding dresses.
From chestofbooks, that accompanied this illustration with the following narrative from Every Woman's Encyclopedia, "...We will turn from the al fresco conditions of the runaway wedding to the pomp and ceremony that attended the marriage of the bride of Napoleon III., the beautiful Empress Eugénie, which took place in the Cathedral of Notre Dame, Paris, in the fifties of last century.
The young bride, whose mode of dressing made her the cynosure of neighbouring eyes, was exquisitely attired. Her dress was one of white terry velvet, with a very long train, and the basque bodice, which was cut high, was ablaze with diamonds of the most costly description and radiant with sapphires. Orange-blossoms mingled their pure loveliness with the gems.

In the Royal Family of France, it has generally been customary to order for the decoration of a marriage toilette lace made in the country. When the Princess Helene of France was married in 1895 to the Duc d'Aosta, she wore an exquisite wedding veil, which measured four and a half yards in length, made of point d'alençon, on the groundwork of which was a beautiful floral design. The centre medallions enclosed the armorial bearings of the bridegroom, surmounted by the Cross of Savoy, the fleur-de-lys, and the arms of France. Her sisters at their nuptials wore lace of equal splendour, and with the heraldic significance applicable to their state..."
