For pre-order drops, it usually takes anywhere between 8-10 weeks for production to finish. This is because the garments that I make are completely custom cut & sew. I explain the cut & sew process extensively on my instagram highlights, but basically instead of using a pre made blank for my shirts or hoodies, I provide the measurements that I would like, and the garments are created using my personal sizing chart. Pieces of cloth are cut from a fabric roll and stitched together to match my sizing chart. Because of this process, and other things such as acid wash, and order volume, it takes around 8-10 weeks to finish production.
If you have any questions I'd be happy to answer them over on my Instagram!
