What is a blouse?
Blouson A short, loose jacket or blouse is gathered at the waist or hips with a fitted belt, elastic, or drawstring. The garment's key design feature is the characteristic slack above the belt. This effect adds volume to the upper body while maintaining a snug fit at the hem.

Historically, the style originated from military and aviation uniforms. Pilot jackets served as the prototype, becoming part of everyday civilian wear in the mid-20th century.
Distinctive features
A blouse's essential element is the hem. A thick, sewn-in belt, wide ribbed knit, or drawstring create a voluminous silhouette and keep the garment in place.

The sleeve cut maintains the overall relaxed silhouette. These styles most often feature dropped shoulders, raglan sleeves, or a voluminous straight cut finished with a cuff.
The classic blouson fastens with a front zipper or a row of metal snaps. The garment is complemented by roomy welt or patch pockets. Collars range from knit, like those of a classic bomber, to a turn-down collar or a neat stand-up collar.
Sewing materials vary depending on the season. Summer options are made from lightweight silk, linen, and cotton. Outerwear is constructed from dense wool, suede, smooth leather, and practical nylon.
What to combine with
Since a blouson creates extra volume at the top of the figure, it's paired with a straight or tapered bottom. Pencil skirts, straight jeans, or classic trousers achieve a balanced proportion.

For casual wear, nylon or cotton blouses are perfect for layering. They're worn over a basic white T-shirt, paired with denim, and minimalist sneakers.

Styles made of smooth wool, soft suede, or thick silk are perfect for both business and smart-casual wardrobes. In these outfits, a blouson replaces a classic jacket and looks harmonious with high-waisted trousers and leather loafers.
When styling a voluminous blouse, stylists recommend avoiding overly full maxi skirts and very wide palazzo pants. Such combinations visually weigh down the silhouette and disrupt the figure's proportions.
