Perfect for daily wear, special occasions, or professional settings, it’s an effortless way to upgrade your silhouette and highlight your best features.
Care Made Simple:
Remove shoulder pads before washing. Wash separately in cold water by hand or on a gentle machine cycle with mild detergent. Avoid bleach. Light fabric softener is fine. Hang dry in the shade or tumble dry low. Do not iron or wring.

Define your frame. Elevate your confidence. Wear your presence seamlessly.
