The 11th Doctor’s “Snowmen” shirt was a lovely component of the costume, although most of it was usually obscured or otherwise hidden underneath the various other layers of the ensemble.
However, I was able to make some important observations about its construction.
Fabric
The fabric itself was both unique and lovely – an off-white base with reddish stripes.
Most easily observable were the thicker stripes, which had a row of small white/off-white dashes (or possibly even threads) down the middle. These thicker stripes were also flanked by two thinner stripes, one close to and parallel on each side.
Centered between these wider stripes was also a pair of thinner stripes.
The shirt fabric also appeared to have some dimensional texture to it (as opposed to just being “flat” shirting).
Unfortunately, I have no evidence regarding the shirt fabric’s composition, so all I can do is hazard a guess that it was probably a lightweight cotton, or perhaps a cotton blend.
Collar
The collar fit was surprisingly loose on Matt Smith.
The loose collar was especially evident whenever he turned his head.
The collar was rather floppy, and presumably uninterfaced, considering the way it crumpled and seemed to have a mind of its own – again, similar to the Second Doctor’s shirt collar.
At a glance, the outer front edges of the collar appear to have been cut with the seams directly on the stripes.
However, a closer examination reveals that the lower front edge of the collar was actually slightly curved.
There was also a row of topstitching around the shirt collar, close to the outer edges – perhaps ⅛” away at most – and very difficult to spot unless you’re specifically looking for it.
When worn upward, the shape of the collar appeared to be that of a “spread collar”; observe how wide apart the front corners were spread.
However, this seems to have simply been an optical illusion; when worn down “normally,” the shirt collar looked to be more of a standard cut – a “semi-spread collar,” at most.
Curiously, there was a small buttonhole on the lower corner of the shirt’s left collar, but not the right one!
Oddly, though, the buttonhole appears to be missing from this particular publicity photo:
Front
The shirt buttons appeared to be “normal” – small, off-white/ivory-colored 4-hole shirt buttons, attached with white/off-white thread.
The front buttonhole panel appears to have been slightly over four fabric stripes wide, although the edges weren’t on stripes; three vertical stripes ran down the center.
Yoke
The shirt appeared to have a back yoke, albeit a shallow one (with the shoulder seam rolled very forward).
The yoke was cut on the crossgrain.
The fabric stripes on the shirt sleeves aligned nicely with those on the back yoke at the armscye seam – at least, on the left side.
On the right side, though, they were a little off.
Sleeves
There were two pleats at the bottom of the sleeve, where the sleeve met the cuff.
The sleeve cuffs themselves were fairly loose-fitting French cuffs.
The French cuffs were quite tall, and of course cut on the crossgrain.
The upper “corners” of the sleeve cuffs were rounded.
