I saw this maybe around 1999/2000? It was in English and definitely a colored movie/VHS. here is what i remember:

A man and a woman are nieghbors. i believe the woman has short, possibly red hair. i think the man was flirty with her? and currently another different woman has gone missing.

Eventaully the man  Kidnapps the red headed woman. she wakes up naked on a table covered in roses, and the man makes some speech. the redhead looks over and notices the woman who had gone missing on another table (i think she had long black hair). somehow that woman has turned into some sort of plant/human. i think the man was trying to “preserve” their beauty? i think it ends with her being locked up in there forever.
