Can I wear short sleeves and suspenders on March 7th?

It's basically ok in the south, but in the north, the weather is still relatively cold, which is better than recommended.

Because the summer temperature in the south is earlier than that in the north, the temperature will be higher. So you can wear short sleeves in the south at the end of April. From Xiaoman to the next solar term, all parts of the country will gradually enter summer, and our region is most likely to enter summer during this solar term, from late May to early June.
