Good luck on finding all the outfits she has worn. She must have been curtsied/bowed to 200x at 200 weddings. I admit I did not like the yellow outfit at WnKs wedding, but I hate yellow. She wore blue and Charles and Andrew's wedding, and those 2 ended in divorce.
Her outfits have elvolved. Now, they look much like one another, but different colors. Quite nice, nothing to write home about. When she was younger she dressed quite dowdy. Her designers, today are smarter or better. Whichever.
I don't know she's worn so many and most of them looking similar +a hat, + a bag and gloves and shoes all the same color plus the sparkly dresses she wears with the tiaras.
