Purchased at Akachan Honpo and washed, but never used. It's a maternity size L. Made of a thin, cool-looking material, and comes with a thin slip dress inside, like a petticoat. I think it can be worn while breastfeeding, so how about it not only during pregnancy, but also for the Hatsumiyamairi (first shrine visit after birth) or Okuizome (first meal ceremony)?
