The thing i love about Miu Miu is all the delicate, feminine, pretty details. The ruffles and pleats and bows and beautiful colors really make this brand stand apart from others. So my opinion is that this bag doesn't have the charm that makes me fall in love with Miu Miu bags. However, i think your bag is classic and could be great with wide leg white or winter white pants and fitted blazers, or a white or cream summer dress. It'd be cute with a denim jacket. I think it has a very specific style.
Unusual to be sure with the texture and color making it stand out. It's very different from Miuccia's current iteration of bags though as mentioned by lilmountaingirl above which makes me wonder when this style was released and how much spillover from the main Prada line was present in Miu Miu at the time.
