This is a 3-piece set consisting of a tiara, necklace, and earrings. I purchased this set to use at my wedding, but I ended up using a different necklace and earrings, so I only wore the tiara on the day. It's a cute tiara with a moderate height. Regarding size and fit: * The tiara can be adjusted by bending it. * The decorative part of the tiara is about 14cm wide, as shown in the photos. * The necklace can be adjusted from approximately 33 to 45cm. I only wore the necklace and earrings during the accessory fitting. Please refer to the 8th photo. Please purchase only if you understand that these items have been used. They have been stored at home by a non-professional.
