This is a very lovely layered top. You can wear the pieces separately, so I think you can mix and match them with your existing items. The size is L. The black long-sleeved undershirt is completely sheer, so it cannot be worn on its own, but it has a slightly high neck and is very elegant. The top is wine red with dolman sleeves. I really love it, so I bought it on impulse, but it wasn't quite what I was imagining, so I've only tried it on. If anyone would like to wear it, please let me know m(*_ _)m #SummerKnit #MixAndMatch #DolmanSleeves #Layered
