✔ 最佳答案
秋裝冬天 - usually Sept/Oct
春裝summer - usually March/April
It is usually because the weather will shift it +/- a month. Like this year the factories are still producing 春裝summer in Sept/Oct; and they have decided NOT to produce heavy jackets for this Autumn/Winter.
If you have been in this trade for over a year you will notice that there are very few new heavy jacket styles available in 香工 this year.
