Robe and Mask
Scream

In the original Scream (1996), Ghostface wears a sparkly lurex fabric robe with square arm tatters and pointed frills on the bottom edges. During production, more Ghoulish masks were considered before finally settling on the peanut-eyed ghost mask. Ghostface primarily wears a Fantastic Faces Weeping Ghost mask, also known as a Gen 1 mask, which is the mask that has the more peanut-shaped eyes, yet are slightly slim. A second mask called the KNB mask was also used in various scenes throughout the movie. The KNB mask was made by KNB FX, and the mask is wider, has thinner eyes, a smaller nose and smaller mouth, along with a lighter neck piece is also worn by Ghostface.
Scream 2

In Scream 2, a copycat appears. Their robe is of the same material, yet has more circular arm tatters, squared-off rips on the bottom hem, and a more pronounced neckline. Ghostface wears a Fantastic Faces Weeping Ghost mask, but this one is a different mold called a Gen 2 mask. The Gen 2 mask has a less curved right-eye, a creased mouth, and more pronounced cheeks. Ghostface also wears a secondary mask featuring squinty eyes and a larger mouth, called the EU MK stamped mask, also coined the RDS. Ghostface at one point wears a leather jacket, and even dons an ancient Greek-style robe.
Scream 3

In Scream 3, the robe is the same pattern and fabric as the one from the previous film. He wears an Easter Unlimited Black and Red Tag Ghostface mask, with the tag on the inside. His mask lacks the former's mouth crease and has more curved eyes. He also briefly hides inside of a prop body-bag.
Scream 4

In Scream 4, Ghostface's robe pattern is the same as in Scream 2-3, and the mask's eyes are slightly spaced apart while also looking more like a pair of curved peanuts, the nose is the same as in "Scream 3", and the plastic has a more shiny and glossy look than previous Ghostface masks. The robes are more shiny this time, with the glitter being noticable and slightly brighter in the lighting of certain scenes. Another secondary mask, called the TD Stamp, is used with wider cheeks, smaller eyes and a smaller nose.
Scream: The TV Series

In the television series of the same name, Ghostface was rebranded during the show's Season 1 and 2, which aired on MTV. Ghostface is now referred to as The Lakewood Slasher, who dons a vacuum-formed plastic human-shaped mask which is painted with white coats, aging glazes, black airbrushing and clear coats. It is then put together by leather connectors with rivets and rectangle rings, connected to aged cotton strapping with weathered and stippled slide buckles. The Lakewood Slasher also wears a black heavy duty poncho, a black balaclava, a black crew-neck long sleeve shirt, (with occasionally a full zip black hoodie), black tactical duty gloves, black jeans, and black tactical jungle boots.
Scream: Resurrection

In Season 3, now airing on VH1, Ghostface is back. The robe is made of a black gauze woven fabric, and Ghostface wears a non-retail EU mask, which has a floppier hood and at times features a shiny or bone white finish and even has a more prevalent jawline. The robe had very loose sleeves, tattered drapes, and no open neckline.
Scream (2022)

In Scream (2022), the Ghostface robe has had a major makeover since the events of Scream 4. Ghostface's mask is similar to the one used in Scream 4, but with a thicker vinyl material and a more deluxe hood. The masks used were the Collector's Edition mask, 25th Anniversary Mask, 2017 EU, and the Season 3/Resurrection mask. The mask's shrouds were taken off and were modified with a custom cotton fabric shroud. In some cases, the actors who played the killer had masks custom molded to their faces. The robe is made of a new material which still features the sparkle of other Ghostface robes but it isn't as noticeable. The gloves are detached from the robe and the ends are ripped. This was done intentional as the costume designer believed it would make sense that the store bought costume would have had major changes in the last 10 years.
Scream VI

In Scream VI, the Ghostface robe remains much of the same as it did in Scream (2022). The only difference is the killer now wears a variety of masks, specifically the masks of all the previous Ghostface killers, starting from Richie Kirsch's mask, all the way down to Billy Loomis' and drops them at the crime scenes. All masks, dependent on their age, have varying levels of decay and ageing visible, with blood and the last time they were worn playing a factor into their look. Richie's mask looked a lot newer and cleaner whereas Billy's had the most visible signs of decay and signs of blood splatter. A normal, white, Ghostface mask is worn by Jason Carvey when he kills Laura Crane.
Boots
Part of Ghostface's look is that the person under the mask is always wearing a pair of, usually black, boots. Each killer wears a different pair at different times and costume designers usually have multiple characters wear boots at different times to set them up as suspects. The Killer's boots have always been a desirable item for fans to identify.
Scream

Ghostface wears a pair of Vintage Brown Reebook BOKS boots. Sidney sees them during her attack in the bathroom where Ghostface steps down and lowers the robe over himself. Billy Loomis also wears the pair in various scenes in the film.
Scream 2
Multiple pairs of boots were used in this film to differentiate the killer between Mickey Altieri and Nancy Loomis. Ghostface's boots that are seen during Sidney and Hallie's attack in the police car are a pair of black Original Rugged Outback Boots. They were identified by Scream collector, Nate Ragon. Another pair of women's boots are seen during Randy's death, in which Mrs. Loomis was the killer, but those have yet to be identified.
Scream 3
Ghostface, who is revealed to be Roman Bridger, wears a pair of black Original Rugged Outback Boots. They are never seen properly on screen, however were identified by Scream collector, Nate Ragon, as he owns a pair of the screen used boots that were presumably worn by Scott Foley. They aren't the same model of boots used in Scream 2, as the ones then were presumably an earlier model with a different sole pattern.
Scream 4
In this film, Ghostface wears a pair of Bates Ultra-Lite Tactical 8" Military Side Zip Black Boots for the most part. However, in different scenes where either Emma Roberts and Rory Culkin would portray Ghostface as their characters, they wore boots specifically matched for their characters. Jill Roberts wore a pair of Rag and Bone High Heeled Boots and Charlie Walker wore a pair of Toto Brown Leather boots, which had platforms in them to make Rory Culkin appear taller.

In the first two seasons of the show, The Lakewood Slasher wears a pair of Black Tactical Performance Jungle Boots. In the Pilot Episode, however, he wears Original Rugged Outback Boots, specifically the Scream 3 model boots.
Scream: Resurrection

In this film, Ghostface wore a pair of Doc Martens 1460 Smooth Mono, which were jet black boots and can be seen multiple times throughout the movie. The costume designer of the film ensured that all characters at one point wore similar boots and in multiple scenes throughout Act 3, Amber is seen wearing a similar pair of Doc Martens however they were platformed. The specific model being the vegan Jadon II Mono. Richie is not seen wearing black boots, but does wear a pair of brown boots.
