Find Your Fit
Answer 2 quick questions and get the size that actually works.
No guessing, no returns. Our fit quiz is built from real customer measurements, not a generic size chart.
1. What's your usual size in fitted knitwear?
2. How do you like knitwear to fit?
Retro knitwear, rebuilt for real life.
You've worn thin fabric before. This isn't that. Every piece is cut heavier, tested for true-to-size fit, and built to hold up past the first wash — so what you buy is what you keep wearing.
Real customers. Real fit. Real fast.
