Batman costume

How do we look like? When we wear the batman superhero costumes, maybe this is the first thing we want to know. Normally, costume is very cool. The important things is that it is suitable or not. Most of time, for cosers, we will buy it in cosplay online store. We tell the saler about our size and they will make it for us. It is no doubt that there should be a little difference about the size. If it is happened in the beginning of the cosplay party. Is there any way helpful?
In such special time, I guess that the only way is to change the size by yourself. Of course, there is not big problem about the size and color. For example, if there is a little hole, you can sew it on. Moreover, you also can send it back to seller and ask for refunding. However, it depends on your needs.
And we all want to have a perfect cosplay experience.
