Instant purchase is OK. I bought this in the summer and had the size altered to a length that would look cute on someone around 150cm tall. I had a professional at a department store do the alteration, so I think it's done beautifully. (The neckline shows less décolletage than the version sold on the official online store.) Please purchase only if you understand the above. The price includes the cost of the alteration, so I don't plan to lower the price.
