To use this Odette long - sleeve top, simply put it on like you would any regular top. The adjustable neck tie can be tightened or loosened according to your comfort. For daily activities, it's great as a standalone piece, and for workouts, it offers good support from the built - in sports bra. When it comes to care, machine wash it in cold water on a gentle cycle. Avoid using harsh detergents. Hang it to dry instead of using a dryer to maintain the shape and quality of the fabric. If there are any stains, spot - clean them gently. And always check the size chart before purchasing to ensure the best fit.
