The birthday girl sash is the anchor here, and the headband and the sunglasses are what keep it from reading as one lonely accessory. Three pieces bought together, so the birthday girl headband is not competing with the sash for attention and the sunglasses are not an afterthought grabbed off a checkout rack.
This is the bundle for the person who wants the full guest-of-honor look without shopping for it three separate times. Everything goes on over whatever she is already wearing, which means no outfit planning and no sizing, and it all comes off just as quickly once the photos are done.
It suits a birthday dinner, a bar crawl, a hotel room pre-party, or a backyard afternoon with a cake on the table. If you have been pricing birthday girl accessories one at a time, the set is the tidier route, and it is a great deal easier to wrap.
What is a birthday sash? A birthday sash is a decorative band of fabric, usually satin, carrying printed or foiled birthday wording and worn diagonally across the body. It identifies the guest of honor at a party and is commonly sold alongside matching accessories such as headbands, crowns, and novelty sunglasses as a coordinated set.
