In short: Pick something simple and good-looking that he will wear every week, with one personal detail, such as a small number, a date or a handwritten line. Keep the balance: not so romantic that it feels heavy early on, not so generic that it looks like you did not try. How much to spend depends on how long you have been together, so choose what feels right for both of you. Check size, exchange and customs before you order.
Not too much, not too little
The hard part is the balance. Too romantic can feel heavy early on. Too generic looks like you did not try. Aim for something simple and good-looking, with one personal detail.
Pick something he will use
A gift he uses every week reminds him of you every week. Clothing, a good bag or a nice wallet beat a gadget he tries twice.
Make it a little hard to find
Small-batch or numbered pieces feel more special than something from the front shelf. They show you looked.
How much is too much?
There is no rule. Early on, keep it modest. After a long time together, or for a big occasion, you can go further. Choose what feels right for both of you.
Check before you buy
Not sure of his size? Compare with a sweater he owns, and look for a free exchange period. Check customs if the gift crosses a border.
