Is it strange to wear boots in this weather?

It depends on the weather in your city ~ ~

However, boots are a fashionable type, no matter when, in which city or in what weather you are, they will not be affected. The most important thing is that you think it is most appropriate to highlight your own dressing style and reflect your personality. After all, this is just everyone's different views and feelings about fashion, so don't care too much about other people's eyes. Maybe, your whole dress will trigger a trend ~ ~
