Vest: eBay (mine: Primark)
Boots: miinto (mine: Safiya)
Luckily, however, they have this adorable green floral skirt that just about fits me. It is a tad short for my liking but it's nothing a bit of clever layering with my tiered lace skirt can't fix. I'm planning to get hold of some wide cream lace to sew onto the skirt's lining so I don't need to do the bulky layering which might get a bit hot in summer.
It's a little odd to be wishing away warm weather, but I can't wait 'til it gets cooler and I can break out the chunky cardigans, long socks and beloved boots. The clothes pictured above are what I own myself, and where I can't find exactly what I have, I've found an image of a similar item.
At New Look I also found the closest I'm going to get to a non-cropped bustier. It's just a lace vest sort of thing by Cameo Rose, but it's of decent quality and is full length, which is what I wanted.
