Dear our clients!. We wrote many times about this difficult question- presents to our girls. We do not recommend to to do expensive presents to our girls before marriage.
You can start to do this only after Engagement.
You can say that before Christmas you want to give some nice present to the girl , which maybe will be your future wife. But It is MAYBE. You can buy the beautiful flowers and nice candy. It will be also nice present for Christmas.
Those our serious recommendations for you, dear men. Please , no gold rings, no gold chains, only flowers and candy.
