I do not get the idea of an excuse that someone is ‘struggling with it’.
They either wear tznius or they don’t, what is “the struggle”?
What about Loshon Hara which I remember reading somewhere that there were 3 mitzvohs that everyone has to struggle with everyday and one of those is L’H’.
Yet I have never seen a heter for saying it, based on everyone having to “struggle with it”.
