Shower Blues

I`m throwing my future daughter-in-law an elegant yet simple shower at a very nice hall. The theme is the problem. I bought simple items like an umbrella, bells and wicker baskets and balloons. My sister was going to make beautiful center pieces out of mums and bows and wedding netting and extra`s. My other sister purchased soap and she was going to wrap them up pretty. I planned on having hershey`s kisses in bowls and nuts. The Hall would cater the food and beverages. I arranged for a beautiful cake with flowers and wishes for a happy life for the both of them. I purchased a linen umbrella for a centerpiece. I cashed in my 401K for the money for this. The shower is six weeks away and now my future daughter-in-law want an Hawaiin party. Somebody help me.
