First of all, we need to clarify why a good briefcase is essential. Whether it's an important meeting or a daily commute, a decent briefcase can carry documents, laptops and other necessities while demonstrating your professionalism and attitude towards life.

Secondly, when choosing a briefcase, size is a factor that cannot be ignored. Different occasions correspond to different capacity needs-a short trip may only require a small and simple design; and a long trip requires more space to accommodate more items. Therefore, please carefully measure the size that suits you best according to the actual use.

Let's talk about the importance of materials. At present, there are many choices such as leather, canvas and synthetic fibers on the market:

• Leather: Durable and high-touch, but the price is relatively high;
• Canvas: Lightweight and comfortable, with a casual atmosphere;
• Other popular fabrics: New materials such as nylon have both water resistance and abrasion resistance.

Make the best decision by combining your preferences with the use environment.

Furthermore, functionality is one of the most important criteria for judging a good briefcase. For example, are there multiple compartments inside for easy sorting and storage? Is there a quick zip pocket outside for easy access to cell phones or keys, etc. These seemingly insignificant details can play a huge role at a critical moment.

In terms of color and style, it all depends on personal preference. Dark colors such as black and brown are usually more stable and formal, which is very suitable for business occasions. Light tones or stitching designs add a touch of vitality and are more suitable for young people's mentality of trying new things.

Finally, let's talk about collocation. Correct wear and accessories complement each other to achieve a multiplier effect. For example, when wearing a suit and tie, it is recommended to choose a classic backpack with smooth leather. However, under casual dress, you can choose more personalized pattern decoration styles.

If you are looking for cost-effective brand recommend, consider some emerging designer brands or series of items from well-known domestic manufacturers. They are often able to give reasonable quotations under the premise of ensuring quality, and also provide a wealth of styles for customers to choose from.
