The 11th Doctor’s “anniversary” waistcoat had four welt pockets: an upper and lower pocket on each side.
Both sets of pockets slanted upward away from center.
And Eleven actually used the pockets; they weren’t just decorative or “for show.”
A particularly nice touch was that the plaid pattern on the pocket welts was aligned with that on the waistcoat body – I tip my hat to the original costumers/tailors for going the extra mile!
Observe that there’s no evidence of any topstitching around the pocket welts, indicating that they were hand-sewn along the side edges.
The precise positioning of the pocket welts may have slightly varied, but the centermost upper corners of the lower pocket welts appeared to be approximately level with the top of waistcoat’s the second-lowest button.
(Alternatively, you could regard the welts as being vertically centered with the second-lowest buttonhole.)
(The dotted lines in the examples above were squared out from the front edge.)
Although the lower front edge was probably cut on a slight curve and the pocket welts presumably on straight lines, the lower pocket welts appear to have been angled approximately parallel to the lower front edges.
The upper pocket welts appeared to be angled parallel to the lower pocket welts, although the upper welts were slightly smaller than the lower ones.
However, there may have been two different approaches to the positioning of the upper pocket welts.
Other times, though, the upper pocket welts appear to have been positioned slightly lower, with the centermost upper corners being level with the buttonhole (rather than vertically centered with it).
(Again, the dotted lines in the examples above were squared out from the front edge.)
Oddly, at least one of the original “anniversary” waistcoats appears to have had slightly asymmetrical upper front pocket welts, with one slightly higher than the other!
It’s entirely possible that either or both of these discrepancies is the result of human error, either on my part or that of the original costumers’, so make of it what you will.
