The reason you see made-to-measure more so with suits as opposed to more casual wear is because suits are highly structured garments. They have to fit correctly in a lot of different places, whereas knitwear like t-shirts and polos stretch and the same size can accomodate a wider variety of body types. There are lots of places that will do MTM casual button ups.
I have several MTM shirts and suits, and honestly I don't think it's really worth it. For a couple reasons, I'm much happier these days finding a brand that fits me off the rack and having it altered if necessary.
1. The grand promise of MTM is the perfect fit, but your first one or two attempts are almost certainly going to leave you with a garment that doesn't fit. At best, this requires more fittings, trips to the tailor, and time. At worst, you're stuck paying for a garment that you will never wear and cannot return.
2. MTM will always be more expensive. For example, Indochino suits are pretty cheap ($400), but for the same level of construction and fabric you're looking at a a $200 suit from Men's Warehouse. J. Crew sells $130 Thomas Mason shirts, and to get the same shirt MTM from my Hong Kong tailor costs me $200.
