FAQ for Women’s underwear sizing
Support, stretch and how to choose when you’re between sizes.
I’m between sizes — what should I choose?
It depends on the feel you want:
- More supportive / snug: choose the smaller size.
- More comfort / relaxed: choose the larger size.
How should a soft bra fit?
It should feel secure without digging in.
- If the band feels tight: size up.
- If you want more support: keep your usual size.
Do the fabrics stretch?
Yes. Merino has natural stretch and adapts to the body, while keeping a breathable feel.
Care & hygiene (returns)
For hygiene reasons, follow your store policy for underwear returns. Keep tags and try on over underwear where possible.
