I'm so weird because for the first few years that I used Lush, lavender always medicinally jutted out at me so it took me years to even dare try products like French Kiss or Waving Not Drowning. I can still smell them once they've hit the water, but I've actually grown to appreciate it in certain products. Love it in AOBS now whereas I hated it before. Don't be afraid of TKO, although I personally recommend getting the massage oil from the Trading Post. Have never tried the perfume oil but I've read that it is more lavendery, hence more medicinal, than the massage oil. You won't be disappointed with the massage oil! It is my favourite lavender-heavy perfume to date.
...anyway, I'll put TKO on my list. :)
I got a bottle of TKO massage oil today and it's amazing. The French Kiss is definitely comparable. I get a lingering sugary smell on my skin when I use TKO, too, which is nice. I'm glad you recommended it!
