I have yet to see or test the entire line of Passion Duo Gloss Fusion Lipsticks in person, but I've found quite a few favorites. Here are the neutrals I have lined up side by side. There's no substitute for testing in person but I hope this helps. For those looking for a good Dolce and Gabbana artist to work with, I highly recommend Nikki from Saks Houston. She's been such a valuable resource to me. She matched me over the phone (perfectly) to their powder foundation and cream foundation. She e-mails swatches when she can of new products. She's amazing at describing colors and textures and gives great ideas on how to coordinate different products. Not to mention her store has great gift with purchases. The minimum purchase amounts tend to be on the high side, but the gifts are very good (often includes at least one full-sized item).
Back to the lipstick comparisons, here are my neutrals swatched left to right: Natural, Sensation, Darling, Feminine, Desireable and Rose.
Dolce & Gabbana Passion Duo Gloss Fusion Lipsticks are $34 each and can be found at select Saks stores and online at Saks.com.
