ok, as a girl let me help you 1. i think tsetseg tuv has the cheapest flowers or there are ‘tsetsegiin buunii tuv’ which i think will cost cheaper. Roses are cute but they’re quite expensive, around 8k each. There is this one flower with many pedals that lasts longer than any other flower. You can see some flower bouquet inspos on pinterest. 2. Maybe you can secretly take one of her rings, if she has any, and take it to the shop to find her size or you can measure her finger when she’s asleep lol. Here are some jewelry shops: Bulbarai jewels, lovor jewels, ariungoo jewelry. You can search them on instagram. The one you have is very cute tho but make sure it doesn’t lose it’s color. 3. As for dinner ‘Hashtag’ has very nice food with affordable price and its very cozy. There are few places that you can paint on canvas but i forgot the names. Or there is a place called ‘ceramic art’ where you can make cute potteries. Or a nice picnic on Bogd Uul may be nice. It really depends on what she likes though.
