The translation of your sentence into English seems a bit tricky because it already appears to be in English, albeit with some grammatical and contextual issues. Below is an attempt to refine and clarify it while preserving the original meaning as much as possible:
"Want to write something but don’t know what to write? Backache? Just go to the 12th floor to see Gigi Leung, Jeremy Scott Adidas Panda Bear [ likely referring to a specific design/collaboration ]. They're super nice. Some girls on TV don't look flattering."
Please note that parts of the original sentence seem disjointed or may reference specific cultural/personal contexts (like "Gigi Leung," "Jeremy Scott Adidas Panda Bear"), which might not fully translate without losing some meaning. Let me know if you'd like further adjustments!
