This is a blouse from Riche Glamour. The size is M. I bought it before and only wore it once. It's in beautiful condition with no stains. It's made of chiffon and is long-sleeved, but I think you can wear it a lot from now on☆ It has gathers and a fluffy, cute silhouette♡ I think it can be used for both casual and dressy occasions. Please feel free to comment if you have any questions (*^*)
