Thank you for viewing! ^_^ The size is shirt L / pants L! I bought these but only tried them on and then stored them away. I think the top and bottom are probably from different series, but since they're black, I think you can use them without any problem♪ I'm also selling other related sportswear＊ I'll give a small discount if you buy them together, so please take a look. 32JE9745 32MF1120
