Thank You very much T_P.. I really appreciate your help...

 

Your are absolutely right about the second model, she is indeed Ekaterina Gudkova... but I think the first one is not Christina Gramazdzina, that Milavitsa campaign is from 2014 and we are searching the model from 2019...

 

 

The first one is correct, here's her Instagram: https://instagram.com/kris___gram
