Little more money but quite nice: http://www.paulstuart.com/product_info.cfm?ProdID=3129&ProdCatId=1056&MainCatId=14&HEADERMENUID=1&SUBPRODCATID=0
I got mine with black grosgrain trimmings. Even in summer early evenings, where there's still enough natural light to discern the colour difference between the trim and the midnight blue, the combination actually looks pleasing rather than jarring. It comes across as a small difference in shade, nothing more than that. And of course, once you're indoors & in worse lighting conditions, everything becomes basically the same colour anyway. Obviously I'm a little biased, but I also have a black tux and still prefer wearing the midnight navy one, so I think I'm being fair to both.
