I think it's something the old generation will insist coz it means something new. My mum actually told me to prepare 12 sets of new clothes too, to wear for 12 days after my AD. But I didnt follow that totally. Haha. Anyway for my bedsheet, it was placed by my husband when my in-laws did the an chuang a few days b4 my AD. Dont hv to hv bridal patterns if ur old folks dont insist on it. We use a normal pink bedsheet instead.
