I bought this last year, but the size didn't fit, so I only tried it on. The sleeves and neck have frills. I think it would be cute to wear it as a sheer top in spring and summer, and as an inner layer under a knit sweater in fall and winter! The size is free size, and I've included the size chart from the purchase site in the photos, so please check it! If you have any other questions, feel free to comment (*^*)
