I think the T was trying, without disclosing anything discussed in therapy with your son, that though you aren't dressing provocatively, your son is affected negatively by how you are dressing. That's different imo. I think also that the dd should dress in her room with her door closed. Your son is in therapy. If these simple things can help him, why not do them? If he's struggling with such things that are easily changed, why not help him this way? Men are quite "visual" beings. And..there has to be a reason for 8 and 9 year old girls becoming pregnant... puberty hits very early now. TC and good wishes.
