What is a plank?
Placket on the shirt - is a detail of a garment in the form of a reinforced strip of fabric, intended for finishing the edge of the lapel and placing buttons, snaps or loops on it.
The main function of this detail is to reinforce the edge of the material. This prevents deformation, stretching, and tearing of the fabric in areas subject to constant tension when fastening the garment.

The placket can be either one-piece or sewn-on. In the former case, the edge of the front is folded inward or outward and stitched. A sewn-on placket is a separate strip of fabric sewn to the edge of the garment.
Main types
Depending on the sewing technology and the purpose of the product, there are several types of fastener design.
- Traditional (American) plank: A visible strip of fabric on the front side, stitched along its entire length. Typical of everyday shirts, oxfords, and casual styles.
- French (smooth) plank: The edge of the fabric is folded inward, leaving no visible seam. It creates a smooth, minimalist look and is used in formal shirts and classic blouses.

- Hidden (concealed) clasp: The buttons are completely hidden under an additional layer of fabric, like a flap. This is the most formal option, used on evening shirts worn with tuxedos or on designer pieces with complex cuts.
- Polo placket: A shortened placket with a few buttons that reaches only halfway to the chest. It's a staple of polo shirts, sweatshirts, and sports dresses.
What to combine with
The choice of a shirt with a certain type of placket dictates the overall level of formality of the look.

Shirts with concealed and French placket...

Items with a traditional stitched placket are versatile and easy to pair with everyday wear. They're worn with jeans, chinos, chunky knits, and casual jackets.
Blouses with a contrasting placket, a different color or texture from the main fabric, make a standalone statement. These pieces look best with a solid-color base layer without unnecessary embellishments.
