hi! how are you? I understand you're looking for an experienced fashion designer and trend forecaster who can design your sporty and streetwear clothing so you can produce them. I have been working in fashion for 6 year now, have had already my own brand, and have the experience needed for helping you with your project. I can sketch, illustrate and also deliver you a technical sheet for the clothing so it is ready for sending to the manufacturer. you can check for some of my designs in my portfolio (https://www.freelancer.com/u/julianademacedo.html), and I can also send more examples of my work, just call me on chat, and we can discuss prices per design.
let me know if you have any doubts.
best, juliana.
