穿绿色连衣裙的女孩是他的姐姐 英语 谁知道

The girl in a green dress is his elder sister.

The girl in a green dress is his big sister.

一般不用wear 要说穿什么颜色衣服 就说in red/green/black（穿红/绿/黑衣服的） 具体什么样衣服就说 in a red dress（coat。。。） 所以答案是 The girl in a green dress is his elder sister.

The girl wearing one-piece dress is his sister.

the girl dresses green is his sister

应该是The girl in a green dress is his elder sister.
