Using our detachable fake shirt collars is a breeze. First, find the top of your blouse where you want to attach the collar. Then, simply clip the collar onto the blouse. It should fit snugly. When you're done wearing it, just unclip it gently. As for maintenance, you can use a soft, damp cloth to wipe the collar clean if it gets dirty. Avoid using harsh chemicals as they may damage the material. Also, store it in a dry place to keep it in good condition. Enjoy adding style to your blouses with these collars!
