What bra can i wear with a dress like this...?

well the dress has a low back so i cant have anything with a clasp at the back. also it has a halterneck so no straps covering my shoulders. also it comes down like a swimsuit top in the front so i cant have a clasp connecting the two cups at the front either? help what bra do i wear with this dress!! its for my school ball/prom so i want to look good (so not bra-less). is it possible to just get stick on or suction cups or something? haha that sounds weird but is it possible. also i live in australia
