Over the past 2 decades, the cost of production of garments has gone down drastically. With brands like H&M and Zara offering clothing for less than $5 people are not really keen on spending money to first buy fabric and then to pay tailors to sew it. One would argue about the economic prudence of getting a bespoke dress done when a mass produced product is available for a fraction of the cost.
Yes it's true that one can buy clothing at very low prices at these brand outlets or even on some China based online platforms but there are many reasons why tailor made clothes are superior to the store bought ones from the perspective of quality to environmental aspects, which I will touch upon in the coming chapters. But one of the most important reasons why tailor made clothing (whether you sew it yourself or get it stitched for you) will always stand way above the ready-made clothing is the “Size”. Customized clothing is based on your measurements. Let's face it, not all of us have a perfectly proportioned body, although the garment manufacturers would love to believe so (we would love to believe that too!) They follow their standard measurement charts for different sizes. You see a small tag at the back the garment that says S M L or 6,8,10 along with the brand label? Those are the size categories the brands have followed. So your upper body might be size 6 or 8 but lower body might be 10-12 or vice e versa. Many people struggle with this measurement mismatch and alter their store or online bought clothes which explains the sudden influx of alteration specialized shops.
Another way to combat the sizing issues is to work with fabrics that are stretchable in nature. Stretchable fabrics are quite forgiving when it comes to fitting and you can easily accommodate two sizes in one garment.
