I have worked in the clothing export field for 21 years and know something about clothing manufacturing.
1, If the clothing is blank, without labels, hangtags, printing, embroidery, or packing, the quality between brand and non-brand clothing is almost the same, if the factory produces under the same standard.
By mentioning the same standard, I mean the following:
1), control the fabric color of each dying jar:
A dyeing jar can dye 800 kg of fabrics. If the fabric is jersey, it can produce about 2,400 pcs of t-shirts. And if the order quantity is greater than this quantity per color, more dyeing jars are required, and the fabric mill needs to control colors even if they are the same color. There are tens of colors for most people, but there are thousands of colors in the clothing field. We use Pantone Color Code rather than saying black/white… to mention color.
2), Use good quality sewing threads. Different quality threads lead to different sewing qualities.
3), Control needles per inch, and use a good sewing machine.
4), Use skilled sewing workers.
Brands generally have very detailed and strict standards on the above, and therefore, brands can keep products at the same quality level.
2, On the labels, hangtags, printing/embroidery, or packing:
Let us talk about facts:
This is the label of brand Polo Ralph Lauren, it uses fine quality woven labels and even used QR code labels (unique labels to check authenticity).
This is the care label of brand Fred Perry, care label shows the brand label under UV light, to let end consumers know that they bought authentic ones.
This is a hangtag of NFL team apparel, good quality hangtag with an anti-counterfeiting sticker.
This is the printing of the brand True Religion. Good printing requires good fastness and a clear appearance.
This is the embroideries of NFL team apparel, which requires good embroidery thickness, and good embroidery threads.
This is the packing polybag of brand Polo Ralph Lauren, with brand info. printed at polybag and a seal sticker at bag opening.
Brands invest a lot in labels/hangtags/printing & embroidery/packing to keep a good brand image.
Given regard to the above-mentioned points, it is reasonable that brands sell at higher prices.
