Wa'alaikum assalam sis! Honestly, pantang set pakai brand apa pun tak masalah sgt, yang penting texture dia soft, breathable, and easy to wash because you'll go through quite a few during confinement haha. A few of my mum friends swear by cotton blends from mainstream brands like Uniqlo or Daiso since affordable and tahan lama, and some prefer the traditional batik or sarung styles from pasar which memang designed untuk pantang comfort. The key is beli yang loose-fitting and easy to change, especially if you're bleeding heavily during the first few weeks.
