YOU SAID:
My brother would like a girl if he wore a ponytail but he cut his hair yesterday so his hair is to short to make a ponytail so I gave him a wig from my old halloween costume so he could look like a girl because that was my birthday gift for him.
INTO JAPANESE
兄は、彼はポニーテールを着ていたが、彼は彼の髪をカット、昨日彼の髪は短いので、かつら古いハロウィーンのコスチュームから彼のための私の誕生日プレゼントだったので、彼は女の子のような見ることができるのでポニーテールにするので女の子に思います。
Well done, yes, well done!
