Clothes tag custom are a way to show customers that their opinion matters and that you care about what they think. It's important because the clothes you wear can say a lot about who you are, so customizing them with your logo or name shows customers that they're getting something unique to them. This makes them feel special, which builds trust with your brand.
Custom tags also help increase sales because they make it clear where to buy it from if someone sees a tag on a garment and wants one for themselves, they'll know where to find it!
