I started off with a couple that let to a very large amount of fragrances for me, almost 40 full bottles plus A-ton of decants and discovery sets. The question here is which scents deserve a spot in the collection which one deserves a smaller bottle like 50ml or 30ml, which ones are good for 10ml, 5ml, 2ml decants and which should you skip all together. So where to start, There’s a base if it’s not full bottle worthy then it’s not worthy as a decant at all as I believe in this statement it’s not a fact it’s just a good base, again it’s just a base. Where I believe the smaller bottles 50ml 30ml is better then the 100ml is when you need less sprays and or your collection is big enough that you can’t wear as often so this way if in the future you no longer enjoy the same scent then you can finish the bottle faster (ex: I have a xerjoff Tony iommi monkey special 50ml as 2 sprays is all I need so if I grow out of it or don’t like it then I didn’t waste the same amount) where the 10ml and 5ml are great is where you enjoy the scent but it’s redundant in your collection and you would have better options like for example Versace Dylan blue there’s a lot better blue fragrances out there so owning a full bottle will get wasted, in this case 5-10ml will do if you still want it. Where the smaller decants come into place is actually testing in different scenarios or just experimenting, experiencing a certain scent profile. for that 1-3ml there’s no way around. agree disagree what’s your take on collecting and what size is your go to?
