First thoughts: It's very light and seems very familiar. Within a few moments, I realized that the Marc Jacobs (black cap) perfume is very similar to this... though this might be slightly less sweet and sharp. La Chase smells less like a perfume and more like a floral scent, which is a big compliment. This would be more likely to elicit the comment "You smell good" rather than "What perfume are you wearing?"
Sillage is light, and it's pretty and innocent smelling in the top notes. Very nice. Since I already have Marc Jacobs from my pre-niche perfume days, I'm not sure that I need this too, but I am very glad to have the sample. It makes me feel differently about Marc Jacobs, actually.
Standout note: Tuberose
Other notes: lime blossom or lemon blossom (but not pure citrus) and very very light spicing.
