White Mini Bag For Sale on 1stDibs

Find the exact vintage or contemporary white mini bag you’re shopping for in the variety available on 1stDibs. Many people prefer White, but fashion is all about individuality — you can find Gray, Beige and more options on these pages. If you’re looking for a white mini bag from a specific time period, our collection is diverse and broad-ranging, and you’ll find at least one that dates back to the 19th Century while another version may have been produced as recently as the 21st Century. Finding an appealing accessory such as this — no matter the origin — is easy, but Chanel, Gucci and Fendi each produced a popular version that is worth a look. There aren’t many items for men if you’re seeking these accessories, as most of the options available are for women and unisex.

How Much is a White Mini Bag?

Prices for a white mini bag can differ depending upon size, designer and other attributes — on 1stDibs, these accessories begin at $195 and can go as high as $20,325, while, on average they fetch $1,450.

Finding the Right Handbags And Purses for You

An integral part of fashion, handbags and purses have been indispensable accessories ever since we began to carry around personal items. Level of craftsmanship, style and shape matters — from coin purses in ancient Greece to early 20th-century opera bags and onward, handbags have evolved considerably over the years to meet our needs and desires, whether or not you happen to be prioritizing functionality over a flashy exterior.

Once, a single “It” handbag ruled each fashion season. No more. Today, lovers of vintage handbags are savvier and have a wider range of shopping options. Nevertheless, classics created by the likes of Louis Vuitton, Dior and Balenciaga still rule.

“It is not a fashion bag — it is a statement bag,” says Mightychic's Debra Kent of Hermès's widely beloved accessories. “When you carry an iconic Hermès bagBirkin, Kelly, Constance — no one knows how long you have been into this culture or if you are a newbie. Your status is validated immediately.”

First released in 1997, Fendi's Baguette rose to fame along with Carrie Bradshaw, the Sex and the City character portrayed by Sarah Jessica Parker. Recently, the design has seen such a resurgence in popularity that Fendi has reissued it.

They are part of design history, so owning a handbag has meaning. As New York–based fashion historian Sarah C. Byrd says, “You have made the choice to invest in this piece because you understand the value of it in the past and in the future to come.”

From a 1980s Chanel black leather quilted mini buckle bag to the rare Hermès Birkin 30cm Himalayan with diamond hardware to a range of 19th-century bags, find a rich variety of vintage and designer handbags and purses spanning numerous brands on 1stDibs — seasonal “It” designation no longer needed.
