Coming in late here (again). Keep the cobalt sweater, it looks amazing. But I wouldn't pair it with the skirt because of the cut: How would it look tucked? Although pic 14 is interesting and would certainly work. I love both sandals, the Suttons being my favourite, but won't they hurt your feet if they are too small? Pay attention to that bottom top strap. The Clarks: I have a similar pair from last year (with denim/leather on top instead of silver), wore them all summer. Not clunky at all, and great for wearing shorts, ankle pants or sporty skirts. But they will absolutely stretch. If they are already too big, that may be an issue. I asked a cobbler if it could be fixed but they said no. I ended up padding the soles of mine with insoles and it made it better... however I am not sure if they will be wearable this year! When they are too big, they impede your step, forcing you to walk a certain way, (subtle, but still), which cancels out any benefit you have from them being "Clarks".
