What do you buy a friend with expensive tastes?

My Asian friend temporarily moved to the UK with her family. A husband and a little girl. They stay in touch regularly. She has expensive tastes and indulges mine every year for Christmas and birthdays. She has plenty of money and I don’t have much. Are smaller things, like glittery hair clips, scented candles and pretty stationary or secondhand jewellery ok? Or should I continue splashing out for her? When everyone else I know wants and gives simpler gifts?
