Caught in the Midi

I don't actually own a loose midi skirt and they all seem to be of the pencil variety due to working in an office environment. Yesterday's weather called for a floaty midi skirt so I pulled one of my Primark maxi skirts (£12) up to sit just above my bra and wore a Primark T-shirt over the top. I also stepped out in my jellies for the first time

I also can't seem to be parted from my New Look necklace as I love the chunky jewels and have a thing about triangles on necklaces. Has anyone else adapted items of clothing to fit a purpose or desired look?
