By layers I'm assuming you mean tiers? Are the tiers stacked or separated? Maybe you can draw out what you remember and show it to your bakery. Remember when looking for cakes, don't look for your colors. If you see an orange and green cake you like it can be done in cream and yellow also. Do a search under floral wedding cakes images and hopefully you'll come across it again. Here is one of many I found. Good Luck.
