For a long-haired dress, I think it is better to match it with a coat, preferably a coat shorter than a sweater skirt, but not too short. Just show the sweater skirt a little. If it is exposed too much, it will look a bit "village" and have no sense of fashion.

You can wear a pair of leggings and tights on the lower body. If you are not afraid of the cold, you can also wear a pair of stockings. I'm not talking about those extra thin stockings, which are a little thicker and can't show your flesh. In fact, if the colors can match well, you can wear striped stockings, but you must match the colors well. If it doesn't match, it is recommended to wear black.

Then match it with a pair of small leather shoes, which can be high or low heels, high or flat heels, or micro heels. As long as it's not that kind of high boots, in that case, I feel a little uncoordinated and disobedient. Because if your sweater skirt is quite long, the high boots will not leak out, which is a bit ugly.
