Speedo for dancing

[speedomeup]

(NB: first time posting a thread and excited for it )

I was recently hired to dance at a private pool party (winter in SoCal, amirite?) and the client asked for me to wear a "sexy Speedo". I only own swim briefs for, well, swimming, so my briefs are not only worn out due to use/chlorine, but they aren't for bringing in the dough in terms of tips.

Any recommendations on brands/cuts for this unusual endeavour?
