The clothing tailor side will give a far more diverse RP option to buying suits, taking the measurements of each customer of course wouldnt change genuine size of the suit but will give a different and more unique way to buy their clothing as we will personally be guiding them through their purchase in an RP sense, instead of just simply looking at a catalogue buying the clothes and leaving with 0 RP.
This would include, taking measurements, asking which fabrics they would prefer, lining details, button quantity, us noting the customers posture over just their standard height and shape to ensure the suits fit them in the best way and much more. As I said it has no visual change whatsoever but that is why we RP. To play out these scenarios
Hope this clears it up
