it’s definitely okay to ask! especially in the context of the situation, she knows you’re buying her a shirt so it’s not just you asking what size she is for no reason. if you don’t want to, id say a medium is a safe bet. personally, id be more offended if i was a size small and somebody got me a large than if they simply asked what size i wore bc then its like.. oh so you think im big huh ?
