Brin,

Staring happens and it is not your problem. We are trying to say that staring happens by all people not just certain ones.

Lechers will stare whenever they like the person, or may stare for other reasons as this process is not just sexually driven.

However, limiting the case to sexually driven purposes, appropriate clothing should do the job.

With all respect, your husband cannot generalise on what men feel when seeing burqa. However, if you accept this assumption, then i don't see why a wide t-shirt/wide jeans can generate the imagination of what is hidden.
