Batman swimsuit:  $5.99 off Aliexpress (RSP:  $10+)

This is actually a knockoff of the blackmilk version, which retails for about $100!  That one comes with a snazzy cape though:

 

I actually thought this one came with a cape too (that's what the title suggested!), but for the price I paid, I'm ok with it.

It honestly doesn't look that great on the rack...the colours are a bit faded.  But once you put it on, it looks amazing!  Just as good as the original.

Except this one doesn't have the blackmilk logo on the back.  It actually looks better that way!  I've already ordered the superman and wonder woman ones for the same price.  They're all about $10+ on eBay, so they're almost half price at aliexpress!
