Define a dress clip.

A dress clip is a type of decorative fashion accessory that was popular during the early to mid-20th century. It is a small, ornamental clip typically made of metal and adorned with various gemstones or intricate designs. The purpose of a dress clip is to hold together the fabric of a dress or other garment, adding a touch of elegance and providing a decorative element. Dress clips come in various shapes and sizes, such as flowers, bows, or geometric patterns, and are often worn in pairs symmetrically on the neckline, collar, or waist of a garment. They can also be used as decorative elements on hats, scarves, or handbags. Dress clips gained popularity in the 1920s and 1930s, particularly during the Art Deco period when geometric and abstract designs were in vogue. They were not only functional but also considered jewelry pieces, often crafted with precious metals like silver or gold and embellished with gemstones like diamonds, emeralds, or pearls. Dress clips provided an affordable way to accessorize outfits and create different looks by simply attaching them to different parts of a dress. While dress clips are not as commonly worn today, they are still cherished vintage items and collected by enthusiasts or fashion historians for their historical and aesthetic value.
