The Princess Diaries 25th Anniversary Collection is ready to rule our closets, collector shelves, and Disney hearts! Twenty-five years after Mia Thermopolis learned she was heir to the throne of Genovia, Disney is celebrating with a royal assortment for fans of the film. This collection is part of the Fanniversary Frenzy merchandise debuting at D23 Marketplace during D23 2026 from August 14 through 16. It will also be available shortly afterward on Disney Store beginning August 17 at 8 a.m. PST, according to Disney Parks Blog.
If you grew up loving Mia’s awkward charm, royal glow-up, and unforgettable Genovian moments, this collection feels like a dream. It celebrates the humor, heart, and history of The Princess Diaries in such a stylish way. Also, if you loved our previous coverage of the next Princess Diaries book, this reveal feels like the perfect follow-up for longtime fans. You can revisit that Disney Fashionista article here.
Mia Thermopolis Limited Edition Doll
Let’s start with the piece collectors will probably chase first. The Mia Thermopolis Limited Edition Doll shows Mia ready to dress, dine, and dance like a princess, with Fat Louie by her side. The doll wears a beautiful white ball gown with delicate green vine details, a sparkling tiara, long white gloves, and sunglasses. Fat Louie sits close, which makes the whole piece feel even more movie-perfect. The display also includes a certificate card noting that the doll is limited to 2,500 pieces. Honestly, this doll looks ready for a royal state dinner and a very dramatic diary entry.
Princess Diaries Ear Headband for Adults
Next, the Princess Diaries Ear Headband for Adults brings royal elegance to park style. Disney Parks Blog lists this headband as part of the anniversary assortment. The ears feature a soft white design with green vine details that match Mia’s iconic princess look. A jeweled tiara sits in the center, giving the headband a regal finish. Therefore, this pair feels perfect for anyone who wants a subtle princess look without going full ball gown. Add these ears to a white dress, denim jacket, or Genovia sweatshirt for instant royal energy.
Grove High School Backpack
Of course, every princess-in-training needs a school bag. The Grove High School Backpack is another item in this anniversary lineup. The backpack features a navy flap with a Grove crest on the front. The body is a light blue shade, while the trim, straps, and drawstring details keep the look classic. The crest includes a lion design with laurel-style details, which gives it a polished school-uniform vibe. I love this one because it feels like a wearable nod to Mia’s pre-princess life. Plus, the structured shape makes it feel polished enough for Disney days or everyday errands.
Mia’s Diary replica
Mia’s diary may be one of the most nostalgic pieces in the collection. Disney Parks Blog describes it as a movie replica with embossed details and the iconic lock. The image shows a rich red diary with ornate embossed patterns across the cover. The word “Diary” appears in gold near the center, while “Genovia” is printed near the bottom. A wide red strap wraps around the book and features a gold-toned crest-style clasp. The clasp includes heart-shaped sunglasses and a “G” detail. Honestly, this feels like the kind of collectible longtime fans will display proudly.
Genovia Pullover Sweatshirt for Women
The Genovia Pullover Sweatshirt for Women is for fans who want to show off their royal loyalty in cozy style. Disney Parks Blog calls it one of the chic choices in the assortment. This cream-colored pullover has a soft, polished look with “GENOVIA” printed in gold across the chest. Below the lettering, an ornate crest design adds that perfect royal touch. There also appears to be a small gold detail near the sleeve cuff. As a result, this sweatshirt feels easy to wear while still making a very specific Princess Diaries statement. Pair it with jeans, leggings, or even a skirt for a comfy Genovian-inspired outfit.
Grove High School Cardigan
Finally, the Grove High School Cardigan brings the school spirit. Disney Parks Blog also names this cardigan as part of the collection. This navy cable-knit cardigan has light blue trim along the neckline, button placket, and hem. Gold-tone buttons add a polished touch, while the Grove crest patch gives the piece its movie-inspired charm. I especially love the varsity feel of this cardigan. It is subtle enough for everyday wear, yet fans will instantly recognize the Grove High School reference. Wear it over a white tee for a casual look, or style it with the Grove High School Backpack for a complete Mia Thermopolis moment.
The Princess Diaries 25th Anniversary Collection is giving us nostalgia, Genovian glamour, and school-day sweetness all in one assortment. Be sure to check the collection at D23 Marketplace during D23 2026, then watch for the online release at Disney Store starting August 17 at 8 a.m. PST. A queen may never be late, but fashionistas should definitely be early for this one!
