Size: No marking (I chose M because it wasn't an option, but it's actually unmarked. Since I almost always wear M, I think it's about M size) Measured flat: Shoulder strap: 11cm Width: 32cm Length: 50cm approx. I fell in love with it and bought it, but I've never worn it... so I'm putting it up for sale (^_^;) As you can see in the photos, there are some fold wrinkles from storage, but please understand this. Thank you very much m(_ _)m. Cups... No cups
