Design Casual Hoodie Line

I’m developing a casual-comfort hoodie label and have the overall vibe crystal-clear in my head; now I need a skilled designer who can translate those thoughts into production-ready artwork and specs. The collection centers on the concept explained below but each piece should still feel distinctive through a mix of unique prints, subtle embroidery accents, and clean custom-logo placements.

Here’s what I’d like to see come to life:
• The concept is that every hoodie design will start with the same drawing, a girl trying to catch a balloon that is flying away and explote it taking her to every posible scenario and customizing it all.

Accuracy is key—especially around the placement and scale of the artwork—so please be comfortable working with neutral palettes and minimalist aesthetics while still adding fresh visual interest. If you have experience producing cut-and-sew hoodies or using 3D garment software (CLO, Browzwear) for fit visualisation, that’s a bonus and I’d love to see examples in your portfolio.

I’m eager to move quickly once the right creative partner is on board, so tell me how many design rounds you include and your typical timeline from initial brief to final tech pack.
