Here are a pile of ideas:
In the Australian movie of Macbeth starring Sam Worthington which was made in 2006, Macbeth was a drug lord and the witches were schoolgirls and very creepy.
In the 1998 TV movie directed by Michael Bogdanov, Macbeth and Banquo ride motorcycles and the witches are bag ladies living in a dump.
The stage presentation at Stratford Ontario starring Colm Feore had Macbeth as a modern mercenary in an African country and the witches as tribal witch doctors.
Or the witches could be Voodoo priestesses if you wanted to give it a Caribbean slant. Set it in Haiti, maybe.
Or suppose the witches are inmates of a mental asylum.
The Patrick Stewart production which was filmed by PBS the witches are nurses and the castle resembles an old-style meat packing plant.
One of my personal favourite possibilities is to have the witches as residents of a personal care home, who sit in wheelchairs cackling.
Or at the other end of the spectrum, they could be "spin doctors" in stylish suits giving Macbeth and Banquo advice on what's trending now.
In order to decide on this you have to decide what part the witches play. Are they real or illusionary? Do they really have the power to predict, or are they talking randomly, and does Macbeth make their prophecies happen? Are they frightening? or just strange?
Once you know what you want to do with them dramatically, you can eliminate portrayals that won't work. The personal care home residents are not likely to be particularly frightening. Once you know who the witches are, then it is easy to know how they dress.
Macbeth.
MacBeth meets the three witches with lady MacBeth
No, the witches are proclaiming and predicting that Macbeth will be king and they are praising Macbeth.
The witches only gave Macbeth prophecies. It was his decision to do so after Lady Macbeth persuaded him. Although the witches' intentions was probably to cause this murder, the witches did not make Macbeth muder Duncan.
the cursed of macbeth was that she will curse witches

Macbeth does.
Lady Macbeth echoes the words of the witches when she says "All hail, Macbeth, that shalt be king hereafter!". This echoes the witches' prophecy that Macbeth will become king.
