see-through clothes
透け 透け透け スケスケ すけすけ シースルー 濡れ透け 透けブラ スケブラ 透けスカート
Clothing or fabric that is partially or fully transparent, whether because of thin or sheer material, or because it's wet.
Not to be confused with transparent or invisible, which deal with see-through objects other than clothing.
Should NEVER be used together with covered nipples. If you can see the color of the nipple, it's see-through clothes. If only the outline is visible, it's covered.
