It is in the section labeled "Racy Uniform T’Ris & Nimhe"
- Give T’Ris a uniform in the evening. BB-2 suggest to register the uniforms at the Station to enhance the impression you want to make
- Go to Station control, they send you away again and ask for someone to “model” the uniform for approval
- Talk to T’Ris, she will go and get the registration. You put her in charge of uniform discipline on the ship
- The next morning Nimhe barges in and complains she has to wear a uniform. After a heated exchange, she agrees, but leaves with her mood reduced
The two bullets points I bolded are the ones that suggest that I should be able to register the uniform sooner, since they occur before Nimhe gets her uniform.
