Leia Organa as a child is seen with Tala Durith's blaster holster
Holsters served as a means for carrying weaponry, most often blaster pistols. During the age of the High Republic Era, members of the Jedi Order utilized holsters specifically designed for lightsabers.
The initial appearance of holsters was in the 1977 movie, Star Wars: Episode IV A New Hope, which was the debut film in the Star Wars original trilogy.
For the Obi-Wan Kenobi show, the props department faced the task of creating a holster suitable for both a young Leia Organa and the adult Tala Durith. This was a challenge for propmaster Brad Elliott due to the difference in height of the actors, and the holster needed to accommodate both Organa's droid, Lola, and Durith's SE-14r blaster. Durith's holster was made as a drop-leg style. For Organa, the team removed the drop portion of the gun belt, achieving a perfect fit. A Han Solo-esque scope was added to Durith's blaster to fill the space where Lola would be.
