Budget
The first thing you want to do is talk to your parents and/or your partner to set a budget. This will help you know how much you can spend on each part of the wedding.
Style
The next step is to talk about what theme or wedding style you and your partner are going for. Do you want it to be whimsical, vintage, rustic, beach-y? This is important to know at the beginning so that you can start planning where and how you want to have it.
Guest List
Creating a guest list with your partner might seem like it is easy but it can be hard sometimes. The first thing to talk about is how many guests you want at the wedding and try your best to stick with that number. This will make it easier for you in the long run because you have to think about seating arrangements, food, and more.
