Should I pick the cheapest darzi?
Pick the darzi whose price you can pay and whose finished suits match what you want. If the work is wrong, the lower quote was not a saving.

A suit, a shalwar kameez, or a formal outfit is a real bill. People type “cheap darzi” or “cheap tailor” because they want the garment stitched properly and they do not want to hand over more than the work is worth.
That search is common before a wedding, a job interview, Eid, or when more than one child needs a uniform. Saving money is a fair reason to compare. It is not a reason to ignore the stitching.

The smallest number on a scrap of paper is not always the smaller bill. A poor fit means another visit, paid alterations, or a suit you will not wear. Paying twice for the same garment wipes out the saving. Look at suits that darzi has already finished before you treat the quote as a bargain.
Ask to see a suit or shalwar kameez close to what you want. The stitch, the shoulder, and the hem tell you more than the quote.
Agree what the price includes before stitching starts: the sew, the buttons, and at least one fitting. A surprise addition at collection is how a cheap job stops being cheap.
A date you can live with matters. A rushed redo, or a suit that arrives after the event, costs more than a slightly higher quote.
In Lahore you go to the shop for the fabric, the fitting, and collection. Sitting for a fitting is how a cheap darzi still produces a suit that hangs properly.
silaaimarkaz does not crown a cheapest tailor. It lets you put a price next to the work. Compare Darzis in Lahore, read the price on the order, and agree it before the stitching starts. Your measurements stay saved, so the next order does not begin from guesswork. When the garment is ready, you visit the shop. A lower price is only a good price when the suit still looks right.
Pick the darzi whose price you can pay and whose finished suits match what you want. If the work is wrong, the lower quote was not a saving.
Yes. Compare two or three prices for the same garment, agree one price before stitching starts, and reuse your measurements on the next order.
