Lady Dior Art

Since 2016, each year, Dior has commissioned about 10 artists from around the world to reinvent the Lady Dior handbag. In limited editions of 100, the Lady Dior Art handbags are rolled out at the Paris flagship store, mid-October. Commissioned artists have included such superstars as Judy Chicago, Faith Ringgold and Joana Vasconcelos, together with young emerging artists.

Unexpectedly, the Lady Dior Art project appeared as interesting to artists, as it was for collectors and the public. In fact, this was an opportunity for artists to showcase their art in another medium, with a utilitarian component, to a new end user, outside of a gallery context. Additionally, the art pieces could cross generations as “hand-me-downs”. Indeed, very few artists ever refused to participate (De Klerk, 2024; Diderich, 2025).

Below, a sample of the dazzling and fabulously re-imagined Lady Dior Art handbags, created by 8 of the 99 commissioned artists, to date.

Oh, patents! The Lady Dior Handbag

Originally created in 1994, by Gianfranco Ferré*, and named Chouchou (a French term of endearment meaning “favorite”), the Lady Dior handbag was rechristened the following year in honor of Princess Diana. The Princess of Wales loved this bag she had received as a gift from Bernadette Chirac, then-first lady of France. She was then seen carrying the handbag on numerous occasions.

Since then, the Lady Dior handbag is history! Originally designed with a black quilted leather pattern (shown below), inspired by the rattan caning of Napoleon III chairs, the Lady Dior handbag has been reinvented many times. For example, the Toile de Jouy** Lady Dior handbag (also shown below) was designed by Maria Grazia Chiuri, Creative Director at the House of Dior from 2016 to 2025.

The US design patent, USD1028500S1, titled Handbag, was awarded on May 28th 2024 to Maria Grazia Chiuri. The Applicant was Christian Dior Couture, in Paris, France. The Maria Grazia Chiuri Lady Dior handbag is made out of an inverted Toile de Jouy-style fabric with the iconic Dior letter charms, and the House name embroidered on the front. The Toile de Jouy for the handbag features a Paris map design.

Below, the patent Figure 1.1 shows a front perspective view of the Chiuri Lady Dior handbag. Beneath the patent drawing, an embodiment of the marketed Chiuri Lady Dior bag, shown in navy inverted Toile de Jouy, with shoulder strap. The image of a vintage, black, quilted lambskin leather, Lady Dior bag, is also included.

Notes

*Gianfranco Ferré (1944-2007), fashion designer with his own brand, was Creative Director at the House of Dior from 1989 to 1997.

**Toile de Jouy is an 18th century, French fabric style made of linen or cotton, originating in Jouy-en-Josas, south-west of Paris. Traditional Toile de Jouy features elaborate pastoral or wild animal scenes that repeat on the fabric.

Oh, patents! Louis Vuitton's proprietary star cut diamond

The House of Louis Vuitton (LV) patented its own proprietary diamond cut, called the Star cut. The LV Star diamond cut was inspired by the iconic Louis Vuitton Monogram flower.

The Louis Vuitton Star diamond cut invention is recited in a family of patents, that includes the US utility patent US2017303647 (A1), titled Cut gem and article comprising such a gem. The patent was granted on October 26, 2017, to Eric Hamers, the French inventor. The patent application was filed by Louis Vuitton Malletiers, in France.

The invention seeks to surpass the brilliance of Princess-cut diamonds by promoting greater light reflection, thereby increasing diamond brilliance. For this purpose, the Louis Vuitton Star-cut diamond has a crown with twenty-four facets, a pavilion with thirty-two facets, and four girdle sides that are identical, each with the distinctive form of an arc of a circle.

Below, an LV diamond solitaire ring, centered with a Monogram Star-cut diamond, and the Star-cut patent Figure 2, showing a bottom view of the LV Star-cut diamond. The scope of the invention extends to gems other than diamonds.

The Abstract of the invention is included below:

The invention relates to a cut gem comprising a girdle (3) having four girdle sides (2) and four girdle corners (1), a table (4) realized by a flat facet, a crown (7) which extends between the table (4) and the girdle (3), in a first direction (H), and a pavilion (13) which extends in a second direction (B), opposite to said first direction (H), between said girdle (3) and a tip of the pavilion (14). The gem is noteworthy in that the crown (7) has 24 facets, the pavilion (13) has 32 facets and in that the four girdle sides (2) are identical in the form of an arc of a circle, the concavity of which is oriented towards the outside of the gem. [Abstract US2017303647 (A1)]
