Layer from the inside out
Quick answer: an opaque full-length base is usually the simplest partner for an open abaya. The best combination also depends on fabric, fit, sleeve volume and climate because the inner and outer garments function as one layered textile system.
Why the base layer matters
An open abaya frames what is underneath. A clean maxi underdress gives one continuous visual line and reduces competing details when the outer abaya already has jacquard texture, embellishment or a wide silhouette.
Science note
Clothing research shows that heat transfer changes with fabric layers, garment openings and the air space between clothing and the body. So adding an underdress affects more than coverage: thickness, fit and airflow become part of comfort.
Polyamide and viscose are different fibre families
Viscose is regenerated cellulose and generally has a stronger affinity for moisture than synthetic polyamide. Polyamide can be engineered into many different fabric weights and surfaces. Neither fibre name alone predicts the comfort of a finished layered outfit.
Hazal therefore keeps general science separate from product facts. The underdress is confirmed as silky polyamide stretch fabric, but its exact percentage is not confirmed. The Turkish jacquard abaya is 100% viscose, while Matte Hawa is 100% Silky Mechanical Polyamide.

Three practical checks
- Opacity: decide whether the base itself must provide full coverage.
- Sleeve volume: fewer stacked layers through the armhole generally sit more smoothly.
- Hem relationship: compare both garment lengths with the footwear you expect to wear.
Frequently asked questions
Does the underdress have a confirmed fibre percentage?
No. Hazal confirms silky polyamide stretch fabric but does not currently publish an exact fibre percentage.
Is viscose always cooler than polyamide?
No. Fibre moisture behaviour differs, but comfort also depends on weight, porosity, fit, layers, humidity and airflow.
