Some wery good advice here, but most men will not have formed the same perspective as you having been broiught up with two busty sisters.  It maybe that mothers should try & teach their sons good manners, but there again I get some of the cruellest remarks from women.

Asfor dressing down my boobs I still find it difficult in mid summer, its really difficult not choosing loose fitting something that's going to make me look several sizes bigger than I really am.

I hear you and you make a lot of sense.  I hope guys take your advice to heart.  I don't want my breasts to be the focus of any relationship!

Ladies of all sizes should read what you just said.  At a lot of social events I go to, I see many women (both large-breasted and smaller-breasted) showing off all they own in low-cut outfits.  They are often the first to complain about bad behavior from guys. 

 Your sisters taught you well.
