Please refrain from purchasing if you are not completely satisfied with the following description. These are custom-made detachable sleeves. I added the jewels myself to the sleeves that were originally made for me. The dress was a gorgeous, sparkling, Korean-style dress, so I further handcrafted them to match. Since I applied the jewels myself, it has a truly amateur feel. I don't think anyone will notice that they were applied haphazardly unless they look closely. However, please refrain from purchasing if you are overly concerned. I think most people will view them from a distance and won't examine them closely, so it shouldn't be a problem. The design is unique and unlike anything else. Foundation was applied to my body when I wore the dress, and some got on the sleeves. I have not had them cleaned at all. Please consider purchasing if you are able to remove the stains. The design is unique, and the back is made a little longer, so it will look fluffy when worn and can cover your upper arms. They were made with elastic, so they should fit arms of a certain size. Due to the foundation stains and the fact that I applied the jewels myself, please do not purchase if you are overly concerned.
