This first gift from husband to wife will never be forgotten. It should be something she will always use and will never forget. It must be something personal.
Being a tomboy does not mean she does not like “girly” things.Does she wear jewelry now? What kind? earrings or a bracelet Now is the time to ask her what were some of her favorite gifts she got in the past. That will point you in the right direction
.Perhaps a new siddur or a set of machzerim. MOST important is the inscription. Your first really, really, personal message from husband to wife.
Most young women will ALWAYS treasure the first gift their husbands give her !!
