It's good, as long as you invite all your dear and near one's, and arrange a good party. However, it won't be like the real wedding. But, it's up to you anyway. All the best !!!
Nothing wrong with an intimate dinner to announce your marriage Surely your relatives will understand.. Hosting a party can be costly & damaging for your flat funds! LOL
Minimalist themes are so stylish yet so simple! If you're saving on expenses, this could be a great theme to follow for your special day. Best of luck!
These are personal preferences. Definitely go with what you're most comfortable with. It's your wedding, you and your husband are the spotlights of the event and you guys should enjoy it the most!
