What is the correct way to write:
Her dress has nice features, like: its black, long and is made by Givenchi.
You should take out like and just put
Her dress has nice features; it is black, long and is made by Givenchi.
Lynne, I would write "Her lovely Givenchi dress is long and black."
Another possibility would be "Her nice, long, black dress is made by Givenchi."
