Saw that when I was at SS a couple months ago when it wasn't on the website. They told me it was discontinued
Anyways, it's way too light to be called midnight blue. SS's colors are off. Even the sales associate said a lot of "their" colors are "their" interpretation and by "their" I think he was implying the Dutch owners.
For an example of their off colors, compare the Blue in the London fit vs the Navy in the Napoli fit. The "Blue" is darker than their "Navy" and the closest they have to a true navy. The "Navy" is a lighter shade of Navy.
I needed a true navy suit for a wedding and they didn't have the "Blue" (ie Navy) in the Napoli fit which was great on me. Instead I just did their cheaper line MTM for $600 which uses the Napoli template but was able to pick the "Blue" color (ie navy). Wasn't bad tho, basically paid $130 more with guaranteed fit
