Mother of the Bride wear 2019

Whats on trend out there for Mother of the Bride 2019 ? What would you want your Mother to wear if you were having an outdoor ceremony (think spectacular backdrop of mountains and sky, helicopter access only) and were having both parents accompany you to the 'altar' ?
My daughter is wearing a modern Pronovia lace gown and tells me she doesnt care what I wear. This is a polite lie haha. She is VERY fashion concious and has a real eye for detail. Ceremony space was chosen for 'the photos', as well as the affinity her and her fianceé have for the outdoors; the majesty of nature.
I am thinking somwthing with q bit of lace as a nod to the bride, nuetral tonings (no bridesmaids to fit in with), and not too slim fitting as I have to get into and out of a helicopter. I dont want to look too matronly either - alot of what Ive been shown is more like Grandmother of the Bride than Mother of the bride ! Im stressing. Pointers please !!!
