Those websites provide you with a platform where you initially select the apparel you need, be it a t-shirt, pants, a skirt, tops and anything else. Then, you will be asked to select the color of the apparel that you need, where you will be offered a palette to choose from. You will be able to witness more colors than what you might get at the offline stores. Then, you will have to select the size of the apparel and from the next step you could start with designing your outfit. Size charts are in place to guide you in deciding the size you require for any gender. Texts can be placed on the apparel in the color and size that you desire. Then, you proceed with placing images or even photographs on your tees. These images and texts can be placed at the front, back, sleeves or any other place where you desire. Once you are finished with the designing process, some websites allow you to have a complete finished look of the apparel that you had designed.
If you are satisfied with the same, you can proceed with it; you can place order for your design in any quantity, size or gender. And, if you are not satisfied with the preview of your product, you can continue with the design process or start designing your apparel again from the scratch. Few of such websites provide a good discount on such orders based on the quantity. So, it would be a good opportunity for you to design your t-shirts yourself, because no one knows you and your thoughts better than you. Therefore, I feel custom t-shirts give us a greater freedom of expressing our thoughts and helps bringing out our individuality. Online shopping is now made interesting through these customization platforms.
