I sympathize about the dearth of different coloured footwear options around these parts. It's annoying as all heck to see they are available across the border but here we have basic black and maybe a dull tan. Ugh.
Anyway, I think you look great in the camo jacket and great in the blouse and the sneakers look fun, too, but I understand the irritation when an outfit doesn't work out as you had hoped.
I am trying to think if I wear a navy column of colour and in fact I do -- quite a lot in winter. One version is with my two piece dress from Comrags and navy tights or sheer navy hose. Sometimes I wear the skirt with a different sweater (also navy print). But I usually wear footwear that's silver, dark red plaid, or black and more "stompy" than the dress itself (for juxtaposition) or else black suede pumps for dress up. This year I guess I can try it with the navy patent loafers. There's not much variation in texture unless I wear the sweater, but they are both prints (very dark prints) so there is that, i guess. Oh, and I also wear my navy puffer with all of that. Hmmm. To tell the truth, I'm not sure this counts as a good outfit! But it's comfortable and easy to wear. And it travels brilliantly.
I also wear a column of navy with jeans and a velvet shirt. That's easier because there is textural difference and juxtaposition.
