Personally I'm more in the camp of modesty. It depends on whether you want him to find you sexually attractive or if you want to get to know him. That dress you linked to is probably a bit too far. I wouldn't call it slutty, but I think you might come across as trying too hard. Dress nicely, but I think you'd be better off wearing something tamer.
It's also worth noting that with a tamer outfit you'll be leaving a lot to the imagination of your date, which can help you come across more attractive. You may remember in memes from a few years back people talking about oversized hoodies being attractive - that is pretty much what I'm talking about, although I'm not saying you should wear a hoodie to your date.
