Is our planning perfect or not? Give your advices

Me(19M) and My Brother(20M) Like Friend are planning to start a new online tshirt selling business. Our main goal is to scale profit slowly slowly by focusing on the premium quality of tshirts. We will be selling 240gsm quality tshirts for now. We have no any experience, but do have intermediate level of knowledge. We will be offering our self made design tshirts and also offering a custom tshirt design option and then we will add more clothing products if it goes as planned. Hope So 🙏❤️
