Fashion changes from season to season. But, in the women's wardrobe there are things that remain relevant just forever. One of these things is a denim jacket (jeans jacket, jacket). They are worn on a sweater in spring, under the cloak in autumn and on a T-shirt in summer.
Denim clothes began to be massively worn back in the 60s, but the oversized style was especially fond of fashionistas in the 90s. By the way, it is these models that are very relevant today. Raw edges and frayed pockets and cuffs will accentuate your personality. Also, you can decorate your jacket with colorful patches, stones, sequins, fringes or prints.
Having a denim jacket in the same color as your favorite jeans in your wardrobe is not a reason to wear them together. Culottes or palazzo trousers would be an excellent alternative. But do not forget, in any image, the main thing is to correctly highlight the accents.
