Engagement Shoot Timing

So I’m hoping to loose some weight before our engagement shoot but I also want to use our photos for the invitations. I want all RSVPs in by August 1st which means I would need to send it out around mid to late June. With this in mind when should I try to do my engagement shoot?


I kind of was hoping to do it in summer but that I don’t think will happen due to turn around being on the slower end especially with wedding in full swing at that time. Part of me then thinks that end of Spring would be better, but my photographer only does week days for engagement shoots and that means it would have to be over spring break as I’m a teacher.
Do I just deal with the fact that I’m heavier than I wanted to be for the engagement shoot and get it done over the fall break (school starts next week for my district), or do I wait for spring break, or do I push it and wait till summer break?
