Whether the card code should be bought large or small is a question that has no standard answer, and it depends on the individual's clothing Xi and preferences.
Generally speaking, the card code is calculated based on data such as height, chest circumference, waist circumference, etc., so if your body proportion meets the card code standard, then you can choose according to the card code. However, if there is a difference between your body proportions and the card code standard, then you need to judge it according to your actual situation.
If you prefer to wear loose and comfortable, then you can buy a size up. In this way, the clothes will be looser, will not tighten the body, and will be more comfortable to wear.
If you prefer to wear slim and slim clothes, then you can buy a size smaller. In this way, the clothes will be more snug and can accentuate the curves of the figure.
If you're somewhere in between, you can choose according to your specific style. **If it is a looser style, you can buy a size larger; If it's a slimmer style, you can buy a size smaller.
In addition, there are a few things to keep in mind:
There may be differences in the card code standards of different brands, so it is a good idea to understand the card code standards of that brand before making a purchase.
If you are buying clothes from this brand for the first time, it is recommended to go to a physical store to try them on first to avoid buying the wrong size.
If you are shopping online, it is recommended to choose a store that supports returns and exchanges. In this way, if you buy the wrong size, you can return it in time.
As a senior fashion designer, I recommend that when choosing a card code, you should consider your body proportions, wearing Xi and preferences and other factors to find the most suitable size for you.
