Couples Pictures... what do I do?!?

Okay ladies.. I have a dilemma. I am overweight at the moment, and I am super uncomfortable about it. However, my boyfriend and I have couples pictures scheduled at the beginning of November because fall is our favorite season. With that being said... what should I do?? Other than being healthier, which I am working on.. I don't know if it's enough time for me to feel comfortable. Should we make it for December and have them Christmas themed instead? Any tips on being more confident? I need help!! Thank you! ❤️❤️
