How many degrees is a thin sweater suitable for wearing?

15 to 25 degrees. Thin sweaters are suitable for cooler weather, usually between 15 and 25 degrees. When the temperature is too high, the thin sweater will be too stuffy, and when the temperature is too low, the thin sweater can't provide enough warmth, so it is a suitable clothing choice between 15 and 25 degrees, which can not only maintain a comfortable temperature, but also show the fashionable style.
