🧵 Fit & Tailoring Tips

Shoulders: non-negotiable—especially in jackets.
Sleeve/hem adjustments are cheap; leaving distortions is not.
Know the brand bias:
- Barrie = oversized
- Nicole Farhi = structured
- Tibi = roomy
Layer Intent: measure how you’ll actually wear it—on its own or with jumpers underneath.

Pro tip: Let Tellar handle the fit math. Avoids guesswork and returns.
