In the conventional impression of everyone, we will feel that long clothes are warmer than short ones, in fact, whether they are warm or not depends on the coat is thin, and then I will show you 9 sets of comparison charts, and you will know the answer.
Comparison Figure 1: A long brown coat and a short black down jacket
Comparison Figure 2: Long gray coat and short coffee down jacket
Comparison Figure 3: A dark gray long coat and a pink blazer
Comparison Figure 4: A white long down jacket and a white short down jacket
Compare Figure 5: Long gray coat and brown fur coat
Comparison Figure 6: Brown long down jacket and beige short down jacket
Compare Figure 7: Long green coat and cropped blazer
Compare Figure 8: Long red coat and short black coat
Compare Figure 9: A long checked coat and a cropped fur coat
Through the above 9 sets of comparison charts, I believe you can clearly see that whether you are warm or not has nothing to do with the length of the coat, generally speaking, whether the down jacket is short or long, it is much warmer than the coat.
