Does anyone think a taste of heaven would be a good sub for invasion barbare because you could get TOH for way cheaper opting for the kilian refill? Seems like they smelled similar unless it's only because they share lavender..
I agree that 1725 is a closer alternative to IB but still,they are all significantly different enough for me.
Add Penhaligon's Sartorial to the mix too if you like the genre,(though the Killian steps outside of it to me).
Test them side by side and see what you think before committing.
