Mashallah Congrats on the purchase.
I also own a city 2013 so feel free to ask questions.
As for poshish i got my city's seat covers from Aabpara market. The shop is just beside the Toyota dealership. They are same as the OEM ones but just a little more beige contrary to the Titan OEM ones. Check my post at this thread (https://www.pakwheels.com/forums/body-work-interior-paint-glass-appearance/207170-car-care-detailing-dreams-part-2-a-279#post3998007) post #5571. Although the fitting is not good but you can have them made at the shop for better preference.
An honest opinion though dont get the seat covers installed as i have noticed that they ruin the natural curvature of the seats unless the seat covers are stitched into the foam like OEM. Enjoy the OEM seats and when they get dirty just have them dry cleaned from any dry cleaner.
Dont forget to protect that Albaster Silver with quality waxes, shampoos and microfibers.
Happy Driving!
