Alright, first off, that sword is stupid as all hell. I appreciate them using the term "longsword" to refer to a two-handed sword, too many people make that mistake, probably due to the longsword in multiple D&D versions being a a one-handed sword for some asinine reason, but goddamn is that sword stupid. it's nearing the level of Guts's "sword", and that was acknowledged as absurd and impractical even in universe. What practical use is there for a sword that long and thick? the length is going to make it unwieldy as hell, no matter how strong you are, and the width means it effectively has no sharpness at all, so it's basically just a poorly designed club at that point.
Secondly, unless you have truly enormous breasts, they aren't going to get in the way of your armor, so all you really need is armor made for a somewhat smaller guy, which shouldn't be hard to find. Heck, even if you did have absolutely massive boobaloos, there are still several very popular styles of breastplate that are shaped in ways that would avoid the issue. Not to mention this is only really an issue with platemail in the first place, since other forms of armor like chainmail would obviously negate the issue in the first place.
Thirdly, Excuse me? You call that armor? You fucking what, mate? What are you protecting, your shagging tits? Oh yeah, I'm sure if they somehow manage to only ever hit you in the 5% area of your body that you're protecting, that'll really come in handy! Christ sake, you didn't even get a bloomin' helmet, you daft cunt, and that wouldn't even need custom work!
