When you get to the tailor expect to be attacked with offers. Make sure you have time, and make sure you have an idea of what you want. Be firm about what you want, but it's OK to hear them out a little. Tailors have an idea in their head about western fashion, they will do what they can to make you say yes. Fitted suits and dresses can be done quickly, but you may pay a premium for for the speed. You'll also have to make sure you book time for fittings to ensure the perfect fit. While I've mentioned that prices can be expensive, it is relative. Pakistani tailors are overall very reasonable compared to western tailors. You're likely going to be able to buy something custom made for half or even less than half of what it might cost in western countries.
The options of types of clothing you can have made runs from full tuxedos, to t-shirts. They will offer to make copies of anything you want, or make something custom for you. It should be noted that copies aren't often just copies. More often than not the copies are inspired by the original, but will have some variations depending on the fabric and skills of the tailor. Go in for fittings of the copies and make sure they fit properly, they may alter the design slightly, even if you bring in the clothing you want copied. Make sure it's right, and if it's not, get them to fix it.
