1. Tote bag/killer bag style
Especially suitable for commuting. If it is a hard-core style, it can be put into laptops/tablets and files, so it is also suitable for formal workplaces. Because it is used in the workplace, you can buy more stable and versatile colors. There are too many brands. Besides Prada, there are many brands with higher cost performance to choose from (for example, Strathberry, which I personally like, is small enough at present).
2. Shell bag
For parties, visitors and commuting, I usually use Tote bag interchangeably, which is suitable for almost any occasion. Personally, I prefer Lu's alma trumpet.
3. Chain bag
Classic Chanel 2.55, grand wedding, cocktail party occasions can also cope, and the girlfriends party on weekdays is also very OK.
4. Soft folding canvas bag
I like canvas bags, fitness and supermarket shopping. Longchamp is the most economical brand.
5. Rectangular business bag with simple lines and larger than A4 paper. Used for interviews, business talks or formal occasions at work, mostly used with formal work clothes.
6. The beige chain bag is used to match dinner dresses and clothes with a small fragrance. It has a small capacity and is not suitable for going out to play.
7 Kimura Yaosi mountaineering bag, I liked it when I bought it, and the quality and comfort are excellent. The only drawback is that they are too big and seldom used. I am going to buy a waterproof sports backpack and throw it away.
Although it exceeds the three guarantees you set, you practice it yourself, so there is really nothing you can't cope with. I have one more because I think it is unrealistic to commute all the year round. After all, from the perspective of changing seasons and bag maintenance, it is not appropriate to bring only one bag for a long time.
