|Three Wishes||1988-1989||Dubbed as the "blue dog" costume, and internally dubbed as B-001, this is Barney's first design, which is a far departure from later Barney designs. Resembling more of a Tyrannosaurus Rex, the body was made with reticulated foam and sprayed with a royal purple dye. Due to the fabric of the foam, it made the costume not pleasant to touch, which made it have the same feeling as sandpaper, as described by Brian Eppes, the actor of Michael, in Purple Tales Podcast. This Barney costume was operated in a similar way to Big Bird from Sesame Street (one hand controlling the bottom jaw with a lever attached inside, and the other in an arm (although if both arms were required, the performer would simply bob the head)). Barney also has a red tongue and a floppy snout. He has eight spots on his back and three on his tail, the eyes and eyelids are also able to move and blink in some scenes. This costume appeared at public libraries and parties. Barney is performed by David Voss and voiced by Bob West. Barney has a deep, mature tone of voice.|
|Waiting for Santa||1989-1991||Internally dubbed as B-002, Barney gets drastically redesigned, with his eyes becoming larger and wider, his legs and belly becoming rounder, his color becoming a magenta/purple, and his mouth becoming smaller. Now, this Barney costume has a new foam body and is Fleeceless. Barney's snout no longer flops. Also, this version tends to bobble and shake a lot more while talking. Now, he has his current number of spots (five spots on his back and three on his tail). Barney's voice goes up a notch to make him sound friendlier than he did before.|
|Barney in Concert||1991-1994||Internally dubbed as B-1, this costume is now made out of Antron Fleece. The mouth mechanism is rare here, almost not present. Unlike the previous two suits, Barney no longer has a tongue. The pupils are also smaller. Barney's stomach has no foam base near the bottom, and his tail gets a little shorter. His feet are given a redesign and the top of his head is lifted even more. Now, Barney is performed by David Joyner, who implemented the "bite bar" method, which is the costume performer biting down on a bar padded with a sponge attached to the inside of Barney's bottom jaw to nod his head, while giving access to both hands of the costume to move simultaneously.
|Imagination Island||1994-1998||Internally dubbed as B-6, this was the first costume to have Barney's arms permanently attached. In this costume, Barney becomes smoother again and brighter. His jaw and his nuzzle are square-shaped as well as his teeth, especially with the bottom row becoming larger, and his body appears rounder. His tail gets a little less curly, making it a little shorter. The bottom of Barney's stomach also gets to a triangular point at the bottom again. The eyes appear much less sunken than the previous costumes, while the blinking mechcanism remains. The toes on the feet appear larger than the costumes used previously and also appear shiny.
|Season 3||1994–1997||This version of the suit is a double of many to be used during this season. Barney's tail becomes less curly at the end than that of the costumes before it. Barney's eyes become bigger and pull closer together. He almost never blinks during this season. Barney's stomach becomes a bit rounder at the bottom. In addition, his feet become a lot less square, his toes come closer to the rubber soles and appear much smaller than the one used in 1994, and his hips and the top of his head become rounder.
|Barney Songs||1994–1997||Another double for the third season. The differences of this costume are in the face. All of Barney's features are more square (especially the mouth) and his forehead is closer to his eyes which really don't blink but move from left to right. The pupils are larger and the eyes are more sunken in.
Later on, Barney's eyes appear larger and his mouth becoming slightly larger toward the chin.
An early prototype version of this one was used as a double for Barney in Barney Live! In New York City for quick entrances and exits.
|Camp WannaRunnaRound||1996-1997||A prototype version of the Season 4 suit, having Barney's feet from the Season 3 costumes. The color seems to come off more pale in this iteration.|
|Barney's Good Day, Good Night||This costume allows Barney's eyes to move left or right. While this function was present in previous costumes, it's at its most noticeable here.|
|Season 4||1997–1998||Barney's reddish-purple color becomes a little darker, his colors overall becoming stronger and vibrant than before, and his face gets a bit of a redesign, with the eyes becoming bigger and fuller than the last costume, and the head shrunken down slightly and becoming even rounder.
|Another double for the fourth season. This costume is very similar to the one above. Barney's neck becomes skinnier and his body becomes slightly like a pear shape. His head is also wider. His teeth are also square-shaped and narrow. His eyes are only pointed to the right.|
|Barney's Great Adventure||1997-1998||This costume was used in the feature film, Barney's Great Adventure. The eyes and eyelids were moveable via remote control to add expression to Barney's relatively stiff face.
|Barney's Night Before Christmas||1998–1999||A slight makeover on Barney's face from the late 1998 suit from the movie; his mouth is now rounder and the eyes are smaller.|
|Come on Over to Barney's House||1999–2002||The costume similar to the earlier Barney (above) used before it. Barney's teeth are thicker and the bottom jaw wrinkles noticeably when at rest.|
|The double costume has Barney with larger eyes, smaller and taller teeth, a squarer mouth, and a rounder body.|
|Season 7-8||2001–2004||Barney's eyes become larger and his teeth become thinner and taller. His head also gets a little smaller/narrower and rounder. Barney's tail also becomes less curly at the end, making it shorter.
|Season 9||2003-2005||Barney's head gets a total makeover, with wider eyes, a wider mouth, square-like teeth, and his hips became less round. His eyelids have become lower. Barney's voice goes up a little higher.
|Publicity photo for this episode, "Singing", from Season 10 of Barney & Friends||2005-2007||This costume is similar to the one in Season 9, but the eyes become a little downward. Barney's toes are separated and his feet appear longer and much boxier than the costumes that preceded it.
|For the Fun of It||2006–2009||This costume is a bit similar to the one above, but this Barney costume has a rounder/wider head and the eyelids are pulled up some. The teeth also become thinner.|
|This is another season to have a double costume. Barney's eyelids been downward and rotated a bit toward each other.|
|Way to Go!: A Travel Adventure||2007-2008||This costume was only used for one year. It includes more of a squarer nose, and connected ankles, only in the back. This costume is even given a lighter shade of magenta/purple.
NOTE: In The Reluctant Dragon: A Fairy Tale Adventure and at the end of The Misbegotten Moon: A Space Adventure, the eyelids are noticeably downwards, making the costume similar to the double Season 11 costume.
|A Bird of a Different Feather: Hawaii||2008-2013, 2019||This costume includes rounder feet, completely connected ankles, a smaller mouth, and a shorter tail to allow much better footing for the performer inside the suit.
