Inspired by a fascinating post linked by
sovay on a nice gentleman who realised that modern Western clothing is very bad about pockets (as is indeed most traditional clothing too), and devised a very good solution, for trousers.
https://sambleckley.com/writing/pockets.htmlI have had the same problem, which is especially bad for women, and found various solutions over the years:
(a) Looser trousers and shorts can accommodate better pockets,
(b) A-line skirts, ditto
(c) For wrap-skirts, the insertion of a little pocket just inside the front flap of the wrap, under the waistband. For small flat things like keycards and bus/train cards. Uunobtrusive, and quite invisible if worn with an overblouse or T-shirt worn outside. A tailored wrap skirt can have a pocket inserted int he side-seam in the usual way. I'm talking about something like a modified sarong.
(d) A friend had a 50s'-style dress made with a wide skirt, and concealed a central front pocket under the centre-front box pleat, like a kangaroo pouch.
(e) An A-line ankle skirt with pockets along the hem, opening at the top - basically a wide, external hem turn-up, stitched down at intervals to make compartments. Both decorative and useful, very handy when sitting down.
(f) Having the internal pocket that men's suit jackets get, included in all my tailored suit jackets, and only buying jackets with external pockets.
(g) For a fitted, front wrap jacket, inserting an invisible, little side-entry pocket into the front over-flap of the jacket. Slanting slightly down internally, so that things don't fall out so easily.
(h) An ankle-length tailored winter coat with wide fur cuffs, with concealed pockets under the cuffs (in addition to regular pockets in the side-seams, obviously). Heavy fabric, so can take bigger things like keys, leather gloves, and possibly a pearl-handled revolver, though I have not yet tried one of those...
(i) Safari and Nehru jackets.
(j) A nice, leather waist-pouch, quite elegant with a long, lean dress, and a loose, unlined jacket over everything - a variant on the traditional external/separate pocket. Hard to find something that looks dressy enough though, you need the curve so it doesn't look as if you're just hanging a box off your waist. One could try Etsy or Alibaba/Taobao. This sort of thing, minus the, in my view, unnecessary logo.
