Once I wake up a bit more, my plan is vintage Jicky, which I'm pretty sure boasts the earliest launch date (1889!) in my collection.
Reminder: 4/9 will be Antiquities Friday...wear the oldest scent you own (you can interpret this as you like — the one you've owned the longest? worn the longest? the earliest launch date? whatever). Suggested by pyramus.
And for those of you who like to plan ahead, see Scent of the day ~ Friday community projects 2021, where I'll try to always have the next five or six weeks mapped out in advance.
Note: the tartan stoneware is by Anta in Scotland. I'm not sure you can still get the exact teapot shown, but they do have lots of teapots (including several tartan models) ranging from £78 to £98.
