What does judging mean?
Nobody’s saying that you can judge others by judging anything personal about a person who doesn’t dress b’tznius or otherwise. Nobody’s making judgements such as does her family dress that way or is it only her, why does she think she has the chutzpah dress that way, etc…
One is allowed to make judgements of others as to how it would effect them. Can my kids play with the kids of someone who does abc or will it have a negative effect, etc.
One can also say constuctive critism, provided that it’s valid.
