For me the beauty of fall is in the changing colors, warming to ambers and ochres. Bride or guest you have a wide range of color combinations to play with and essentials to explore.  Here are some of my faves . . .

Top and second row: Head pieces from Moth and Bay Leaf
Third Row: Autumn Leaves Clutch from Atelier Edyta Loukia
Fourth Row: Magical Evening Earrings: Divina Locura
Fifth and Sixth Row: Chantilly Lace Tutu Skirt by Tutu Chic
Seventh Row: Jazz in Autumn Maxi Chiffon Dress by In June
Eighth Row: Olivian Rosary Necklace by Mona Abraham
