She manages to be period-accurate with a very Harley pin-up twist. The black and red bra could fit right into any underwear campaign, and the khaki hotpants are not an army-issue pair, but Harley would never fall in line wearing regulation attire.
In Suicide Squad, Harley continually survives intense fights and always seems to be in the right place at the right time. Most of her team also survives the fights, so maybe the reason for their success is actually their teamwork. But if the theory is correct, Harley survives because she is lucky.
The Joker himself is immune to most if not all strains of Joker Venom (a possible side-effect of his own constant exposure to and abuse of his chemical weaponry).

She effectively killed Superman before he ever got a chance to become the hero he was meant to be. While it's not as impressive as defeating the Last Son of Krypton in his prime, killing Superman is something that technically puts Harley in the same league as Doomsday.
Despite appearances, Harley Quinn has been able to go up against (and defeat) powerful opponents like Lobo, Black Canary, and even Superman. One of her most defining traits is her unpredictability, something she often utilizes to her advantage against stronger opponents.
While the two worked together for years, the only one keeping any semblance of a relationship alive was Harley. Truthfully, the Joker was never that interested in Harley, save as someone he could easily leave holding the bag during his criminal endeavors.
