My boss says that I'm to revealing.?

My boss says my low cut blouses create issue in the work place. Let me explain, about 12 yrs ago I had female issues that resulted in a hysterectomy. Just prior to this I look awful, i was only 26 when this came to be, now however i finially gained some of my weight back and i'm starting to look desent and being in the past i looked a broom stick wearing a shirt but now everything is starting to fall into place. not that i'm ready for playboy or anything but instead of hearing "you need to gain weight," i hear " you look nice today or you don't look your age." it has given me back my self esteem. now about my boss she is old, fat and ugly. she is all the time making comments about my figure, at least a dozen times a day. My blouses are either to low cut she says or they are to tight. i work in an office with just me & her, rarely does anybody come in there. not to mention my husband doesn't have a problem with what i wear why should she?
