Oh dear.
I hadn't even thought about that. I know my inlaws won't ask but I guess its one of those unspoken rules that no one talks about until after the event. For my engagement we gave all the women that came with them for the engagement ceremony Suits incl' suits for my SIL and MIL.
But I guess for the wedding I would give a gold earrings to my MIL and either a ring or gold earrings to my SIL, seeing as I will be paying for them, that's all I can afford. If they are not happy with that then that's their problem.
I have been reading your responses. I want you to know I admire your courage to take on your entire wedding with such maturity and grace. We need more women like you around.
Allah bless.
