Thank you for viewing! I've added a new, romantic collar piece to a new, ready-made dress. There is no lining, but I don't think the material is see-through. It's new, but there's no tag, so I don't know the material or size, but I believe it's a free size made of mostly cotton. Please consider it for the coming season. ☘️ Flat Measurement Size ☘️ Please allow for some error Width (between armpits)……48cm Length (from the top of the back center to the hem)……86cm Sleeve length (from shoulder seam to cuff)……54cm ⭕️ Immediate purchase without comment is OK. ⭕️ Silent transactions are OK (please rate after arrival) We will pack the item to minimize damage as much as possible, but we will use simple packaging that is compressed and lightweight. Please understand that there may be folding wrinkles that occur during packaging. We will ship via either Yu-Yu Mercari or Raku-Raku Mercari, but we may change it at our discretion without notice. Please understand. I may not be perfect, but I will strive to have smooth and sincere transactions, so thank you for your cooperation. I hope we have a good connection.
