Girly baby shower??

So I wanted some ideas/advice!! My DH and I will not be finding out the gender of our baby because we want it to be a surprise. But I've always dreamed of a whimsical, pink/black/gold Kate spade-ish baby shower. What are your thoughts on have a "girly" baby shower even if I do not know the gender. Will people think this is odd?? Or should I just do as I want? I know I shouldn't care what people think but I am just unsure if there is an "ettiquette" or guideline to decor...I don't want to stick to the typical neutral yellows and greens. Thanks for any ideas or advice ladies!!
