A coat is definitely your best choice. In autumn, it is a very good choice to put a coat over the half sleeve, because our arms are easy to catch cold, and a coat can better protect our arms. Most coats can adjust and protect themselves. For example, in the early autumn, you can choose some thinner windbreakers, and then you can choose some thicker jeans and windbreakers, which are very good choices, and most of the clothes inside don't need to move.
Autumn needs a thinner scarf. It's really cold in autumn in the north, and the neck is often unguarded. If you wear a scarf that is not very thick at this time, it is really appropriate and really elegant.
Here are some popular models. Although they look terrible, they look really good together. Or you can buy some strange masks, or you can keep warm, which is very practical.
A pair of boots keeps you from worrying all autumn? In autumn, boots are really important. No matter what kind of clothes, you can wear jeans or some skirts in your daily life. They are all versatile and can be worn for a long time. In fact, if you don't choose boots in autumn, you will definitely regret it.
Here are the boots. I recommend some combat boots, or some Martin boots and some designs that have become mainstream recently. They are very nice, and you should buy a slightly thicker one, because it can take a lot of time to wear in spring. Boots may be a little heavy, but I think they are much better than high heels.
