I am not sure if this qualifies as a "cute colour combo" but it reminded me a bit of the last outfit in that series that uses the same pattern for suit and top, except in different colours. Although here, I'm not playing with colour, the idea is related. I'm picking up part of the (rather busy, colourful, and already very mixed) pattern and repeating.
This is an unmatched, surprise set. I was putting away this just-laundered Sandwich top when I noticed that it essentially echoes the white-teardrops-on-navy portion of the pattern that appears in my Boden pleated skirt. Could it create a kind of "matched" set? Bingo!
An irony -- I bought this very-much-on-sale top as a way of getting free delivery when I ordered a skirt and another top from Sandwich earlier this year. Unlike the skirt (which I haven't even worn yet!) it has already proved itself a workhorse, just as its similar, sister top did last year. (Same general style, except the other top has a straight, not bloused hem, and is a different fabric -- woven vs. knit.)
As usual, my apologies for the lighting...I do my best.
