partner keeps pushing me to "improve" before our next club night and i dont know how to feel

im 33f, dh is 36, weve been in the LS like 14 months. our next big club event is in 6 weeks and dh has started making comments like "if u wanted to drop a few before then i could help with meal prep" and "have u thought about getting some treatments done" and offering to pay for various things. on its face it sounds supportive. it doesnt land that way tho. it lands like he's telling me my body needs fixing before its acceptable to show up. i havent confronted him directly cause i dont want to start a fight before a fun night out, but also im starting to dread the event itself which is the opposite of why we go. has anyone been on either side of this, like has ur partner pushed u to change ur body for LS context and how did u handle it, or have u been the partner who pushed and looked back and regretted it. i want to read this carefully before i say anything
