I don't mind Benefit's packaging at all... yes it's cardboard, but it holds up, and I think it looks more retro than childish. Maybe I've gotten too used to Korean makeup, which is extremely high quality but very... colorful. Also, Bobbi Brown has just always been one of those brands that are so amazing, you use no matter how it looks, lol.
The ones I never go for are the "old lady brands" like Lancome, Elizabeth Arden, and Estee Lauder. I love Estee's gorgeous personalized powder compacts, I have one that's a gorgeous moon & stars motif with a beautiful "mood"detector in the middle and two or thiree different versions of their Aries compacts, but everything else is so... ugh. Actually, Estee is starting to really get their packaging right, they have some products coming out for the holiday season that just look gorgeous. It's frustrating, though, how these three brands have the best GWP but awful packaging. As a total aside, it also frustrates me that it's always "with any $35 purchase..." which sounds great, but then all of their products are either $30, $32 or $50+, meaning you really have to spend $65 to get the GWP, haha!
I have never tried the Calvin Klein cosmetics for this reason, too. Boring! Napoleon Perdis, Lorac. I never try Cargo for this very reason, too.
But honestly, you guys should try Benefit! I spent about $4000 on makeup this last year and they're one of my favorites. Also, give me Guerlain and Tom Ford or give me death!
