Over the long months trapped in space, Bishop’s hair grew out and he wore it as dreadlocks. Shortly after his return to Earth, he was abducted into a future timeline. His costume torn, he had to use what little equipment was there and came up with this makeshift creation. [Uncanny X-Men #372, Bishop – The Last X-Man #2]
After the X-Treme X-Men left the mansion, they came up with a set of new costumes, mainly in red and black. Like the rest of his team, Bishop has a special set of sunglasses with special properties (contacting each other, scanning, etc) and additionally he carries a pair of plasma blasters through which he can channel his personal energies. [X-Treme X-Men #1]
last one... and my favourite. :>
edited to add it is not my intention to 'steal' the thread from jury copeland. just adding to it, is all.
Wolfsbane (2nd of 7)
After their traumatic experiences at the Beyonder’s hands, Wolfsbane and her teammates were sent to Emma Frost for help and briefly joined their Hellions and wore their typical uniform: a tight, v-necked suit in two shades of magenta with a white triangle symbol over the heart. [New Mutants (1st series) #39-40]
Wolfsbane (3rd of 7)
The New Mutants sneaked out, using their intended graduation costumes (which, unlike their standard uniforms, had masks) only a few times. Rahne’s uniform consisted of an orange leotard with black sleeves and tights, an X-belt, simple orange boots and gloves and a fitting mask, which left the top of her hair free. [Uncanny X-Men Annual #10, New Mutants (1st series) #54-55]
Wolfsbane (4th of 7)
After the tragic death of Cypher and believing the X-Men to have died as well, the New Mutants decided to graduate and put together individual, albeit somewhat ragtag costumes. Rahne’s uniform was basically a one-piece, dark brown leotard with boots, gloves and a pattern in lighter brown. [New Mutants (1st series) #61]
Wolfsbane (5th of 7)
Boom-Boom redesigned everyone’s outfit after a stay in Asgard, so that they’d all have individual, yet similar costumes. Rhane’s outfit was an orange-brown suit with white thighs (all uniforms had that in common), white gloves, shoulder pads and an X-symbol on the chest. [New Mutants (1st series) #90]
Wolfsbane (6th of 7)
As a Genoshan prisoner, Rahne was made to wear one of their skinsuits. Later on, her head was also shaved and a number tattooed on her forehead. During the mutate bonding process, the suit was fused to her skin and could no longer be removed. Fortunately, it was not visible whenever Rhane was in wolf-form or a transitional state. [New Mutants (1st series) #96]
Finally...
All X-Factor members wore individual blue and gold designs. Rahne’s was a short leotard, which left her legs and arms free and had a huge X-symbol on her chest, combined with clunky dark blue boots. When Rahne was able to switch back to her human form again, she sometimes added light blue tights against the cold, though they would disappear whenever she was in furry form. [X-Factor #72, 102] Rahne continued wearing the outfit, even after she left X-Factor to join Excalibur.

After a battle, Warren was found unconscious in the Savage Land and given this new suit by a mysterious benefactor, who was none other than Magneto. [X-Men (1st series) #62] It was only later discovered that the costume was slowly leeching off Warren’s mutagenic energies for Magneto to use. [Avengers (1st series) #111] With the equipment disabled, Warren continued to wear the outfit.
Shortly before the Champions had their first press conference, Warren’s costume was torn in a fight. His agent tried to replace it but, by accident, he came up with a version of the Angel’s former costume and the colors were wrong too. [Champions #8] As time was of the essence, Warren had no choice but to wear it, but came to like it. While he was serving the Champions and later on helping out the X-Men, he wore the outfit with yellow gloves and boots. The version presented here (white gloves and boots) is from his days among the Defenders.
Long months later, when the original five X-Men reunited, they came up with the idea of X-Factor. To the media, they acted as a mutant hunting group, while secretly they were trying to help mutants to handle their powers. Warren wore a backpack that to the public seemed like an important piece of equipment, while actually it was meant to hide his wings. In situations that required the use of their powers, the team used the cover identities of the X-Terminators along with a new set of costumes. [X-Factor #1-2]
