I'd only wear knee high heeled boots with that dress (and it would actually look great with my Chloe boots, Mango outlet, you say...), can't think of other footwear that would work for me as it would be a few cms away from maxi length on me (potentially I could get away with some ankle boots at that length but it'll be one very specific pair).
Mules like attached (but probably not black) would work but only indoors/really mild weather. If I were taller with slimmer reading legs I would probably try flats but tbh I always find that while it looks fine it always looks detached somehow, as it does on that model (but my deep dislike of American preppy shoes may be showing here).
Combat lace up knee high boots could work if you get the proportions right, but that part isn't going to be all that easy (though I suspect easier when you're taller than me).
Riding boots could work but you're going to end up looking heavy of calf, but it won't be that noticeable in the scheme of it but it will read overall as slightly sturdy.
