Can I use Sports Tape or 1st aid tape wrapped around me as a makeshift sports bra?

I have D cup sized and I am training very hard and loosing a lot of weight very quickly, I am having to buy a new sports Bras every 3-6 weeks and really need a cheaper option. I have seen women tape their s down and I have also seen a sport tape which is meant to help with injuries but also help train better (can't remember what it is called). any recommendations....
