--) Mutant X's Storm wore the same costume as Earth-616's Ororo Munroe when first joining the X-Men, before becoming a vampire and Bloodstorm. Since X-Men: Blue's Bloodstorm was a vampire before joining the X-Men, it's unlikely she wore that uniform.
1) Storm adopted a leather biker look for her costume as the vampire Bloodstorm. She wore black pants and boots, a black leather jacket, and a small sports bra underneath. She had a traditional red and black 'X' insignia on her belt. [Mutant X #1] The second Bloodstorm had an almost identical attire. [X-Men: Blue #10]
2) During the Mothervine crisis, the new X-Men team adopted matching costumes. Bloodstorm wore a slightly different look with black leggings and a black sleeveless crop top with a blue 'X' on the chest and on her boots. [X-Men: Blue #25]
