I think I made some suggestions about a year ago but I found one of my much older posts (and related comments and suggestions by others) from ~6 years ago. Some info outdated, some still current:

The Elise recommendation still seems current and relevant. I didn't check any others.

One of my biggest complaints about photoshoots is the failure of the photog or the assistants to pay proper attention to twisted straps and wrinkled or uneven panties. If the time and place are mutually convenient, I will volunteer to provide oversight of those details and to untwist the twists and smooth the wrinkles before the snaps are wasted. And my cell phone has a really good camera so I can provide you with some extra snaps at no charge!

Good luck!
