Everyone has their own idea of what "dreamy/feminine" might be like. What is the recipient's idea of dreamy? Maybe it's more of an ocean/water theme; or floral; could be fairy-like or butterflies; lace ... Perhaps she should pick out a focus fabric that says "dreamy" to her, and you could design around it.
