My take on this is it's not necessarily the LV monogram itself. If you considered a monogram canvas of another brand, say Gucci, Dior or Coach, would that be too loud? Or any other heavily patterned bag for that matter. LV at least has the historical standpoint that, even though it's a loud noticeable item, has some history and regard to its products that tone down the overall statement of the product you are carrying. Only you can decide whether you are comfortable taking such a bold item to work. That could be statement shoes, coat, trousers, etc..
