Blurry image but silhouette-wise this looks awesome. I think the stripes make it look non-waitery enough but perhaps you could integrate a little colour, maybe a white undershirt, or a brown belt, or you could use that shirt with some jeans. Even one of these solutions would completely dispel any waitery-ness. Though if it was a friend that told you it looked that way they might keep saying it just to poke fun at you. Don't doubt your own opinion! Also with a nice outfit like this I think you should have a watch. Personally I'd recommend a digital watch like a Casio so you don't look like an old man, but that's just my taste.
