logo design challenge - lingerie website with a long name

http://www.PlusSizeBrasAndPanties.com

I operate an online website of lingerie for "big" gals. I have been live for 3 years and now feel it is time to add some fine design.
I am from the film industry so work in a very visual way. I like details and balance within design.
I want this to look like a small upscale boutique not an online gambling site. I want a lingerie site that is not in the erotic category. I want elegant, pretty, sensual, approachable, fashionable, eye catching and memorable.
I have been using a photo of a passion flower to date. I liked the color, I liked the "passion" name and it was feminine. I will eliminate it once a new design is done. It could be incorporated or not. I am not tied to it.

My target is Plus size women with hard to find fitting issues. I have a steady customer base but want to attract new customers as well as present myself more stylishly. I want a design that can be used away from my website as a promotional tool.
I want to show pretty, attractive and clean. I sell an affordable product but am adding some more expensive items. I am educational in content.

I need inspiration. I need some guidance. I need ideas.....

I like the color scheme on my website but would be open to color choices on the logo. I am happy with the fresh look of the yellow and purple.

My name is very long therefore will requires some creativity to invent a good logo. I need letter diversity so that "sandpanties" is not highlighted.

I want a feminine style but not too fluffy. I like clean lines but also enjoy a slightly vintage appeal. Some inspiration may be historic corsets and the beautiful tiny details used. The hour glass figure and heavier woman works for my clients. No hints of skinny models.

I like the "french style" being seen a lot now but not AS busy as in the postcard logo I have included. I do like this slightly retro style and french implies fashion, sensuality and women.

I want a unique logo that becomes my brand.

I must be able to load it onto my website header. I also want a condensed button and banner for display on other pages.

I really am very open to ideas. PLEASE HELP ME......
