Uzaki's character works off of a NTR system that I eventually put aside to focus on getting things to work. Try running the first and second challenges again, intentionally making the wrong choices, and see if it allows you to use the third outfit

Very strange. Honestly don't know how to explain that. You're the first person I've seen have this issue. I'll have a look into it and see what I can figure out. Last thing I can suggest in the meantime, is to play the first two challenges again on the same save and see if it allows you to unlock it. The wrong choices add to a value that unlocks it. Best of luck, I'll let you know ASAP if I figure it out.
Having a look over the values, I honestly don't know what to say. There is a safeguard built into the game so that the wedding dress would immediately become available after completing level 2, even with a bad outcome (currently due to a bug, the only possible outcome). Potentially silly question, I assume you have the paid version of the game purchased and downloaded, and not the demo by mistake? The wedding dress outfit is not available in the demo.
Okay i managed to get it, but it was pretty confusing? Like i could only get it only after the second challenge but before the 2nd intermission. if i tried to play it after it just say locked.
It also broke up the plotline i think? Like there was supposed to be a segue into her wearing the wedding dress but there's nothing
