All three ties look naff, and the pinstripes on the suit are the exact wrong kinds of pinstripes. Nevertheless, I would keep the suit for now and focus on the rest of the outfit. If you're fond of the white-on-white look, I suggest you look into mid-gray ties, which look less goofy while still offering that soft contrast with the shirt. I would also strongly advise you to get your hands on a white linen or cotton pocket square. This kind of formal rig really calls for that.
