Hummm, if I was told I could only keep one lip product, it would have to go to Elf's Perfect Pink Lip Tint. That's not a gloss but it goes under every single gloss I wear so when the gloss wears off I still have a pretty pink color on my lips.
I have three in various stages of use (one in the car), and just discovered I only have 3 unopened ones left
I don't think I could rank them. Maybe the Dior 465 Shock or Pat McGrath Pale Nectar Fire and Too Faced Hustlin'
Thanks @Squirrels Are Trash That was fun

And another favorite non pink but is soooo pretty over the Elf Perfect Pink
is Too Faced Dance Off Pants Off

For some reason, when I wear the Too Face Pants Off Dance Off
I feel like I have to wear Kayali's Musk perfume. Can't explain it. And it's been discontinued
This is the perfume I'd choose to keep if I could only have one.
