Lucy Hooper's Paris letter to the Baltimore Gazette contains this accotrttt of an American girl's dress: A good many of our American visitors have taken wingto London, some on their homeward journey, while others go to enjoy the London season or to be presentad to the Queen at one of the two drawing-rooms, which are all the ceremonial that Her Majesty will vouchsal'e to preside over in person this year. 1 have just had the pleasure of inspecting a magniücent court dress niadeby Leroillant for MissEmily Scboumberg of Fhiladelphia, who is to be presented at the second drawing-room by Mrs John Bigelow, Miss Welsh being unmarried does not present the American ladies at court. The dress in queation is entirely composcd of rich white satin. The front of the skirt is trimmed with wide chenillefringe, with a heading of fine silver net, and vi tli bands of large daisies and green leaves in chenille embroidery. A band of similar embroidery edges the Iow corsage. The train is three yards in length (the regulation length as prescribed by etiquette), and is cut around the edge into large seallops. At the upper points of each scallop is set a daisy with its leaves in chenille embroidery. This train is laid in Hat pleats on the right shoulders and is clasped there by a single large daisy, crossing the back of the corsage transversely and being held down at the lef t side of the waist by another cluster of daisies. The method of arraying the train is far more gracef ui than were the Watteau pleats. With "this dress Miss Schoumberg will wear a full set of diamonds, comprising three bandeaux for the hair, a necklace of fine single stones, solitaire earrings and porte-bonhem bracelets. The regulation three white feathers and tulle veil will complete this riel and tasteful toilet, which will show to great advantage on the tall, slendei figure of its beautiiul wearer.
