The size is 110. I bought this for a piano recital. Therefore, it has only been worn once. I will also include a pure white blouse as a set. I think it can be worn for everyday wear, as well as for formal occasions such as weddings and recitals. It may be difficult to convey in the photos, but it has a very cute and elegant feel. Both items are like new and are in beautiful condition. Thank you very much.
