Believe it or not, I always try to find a complimenting lotion to my perfume. Since my HG perfume is Burberry Tender Touch, it actually compliments the Johnson's Baby Lotion nicely
I layer whatever smells I like. I layer everything. I wear like baby lotion or jergens and then I put on Victoria's Secret body spray..it might be endless love or something (it's blue) and Bath and Body Works cherry blossom. When I feel like it I'll wear fantasy in apple on top. Sometimes I'll wear a real perfume along with it (like if I'm going out or something). I aaaaallllways wear more than one scent.
I also try to layer my scents, especially the ones I wear allot, I have sooooo many that I don't have lotions for (I went on a major fragrance haul after my ds was born because nothing seemed to work w/my chemistry) I also try not to layer the 'heavier' fragrances.
Never, even if the scent complements my perfume or lotion. I feel the smell would be too strong, and I hate those women who pass by and you feel like a humongous wave of smell coming to you.
Usually I use the same body wash, lotion, and body splash. But if I don't have a body wash for a lotion or something I make sure I use a very light body wash and lotion. I can't have my smells mixing HAHA!!
I always forget to put perfume on, so I've been orderering dupes of my favorite perfumes from etailers & just using the lotion instead. sometimes I will wear my after tanning lotion with perfume, but I think the scents are both pretty light & I don't really care if they complement each other, they smell good by themselves so I figure they'll probably smell good together!
