Completely fell for this sheer train on Christine Centenera! A. This piece (a skirt or a jacket?) that hangs like a half sheer maxi is amazing and I love that we still get to see her legs. It would be a very easy DIY too! Buy some sheer black fabric, cut to desired width and length (just touching the ground when in heels is perfect), hem in you choose, and then tuck into the waistband of a black bodycon skirt. Wear a jacket over the top of create the illusion of a jacket.

In terms of where to get your fabric - I often buy gorgeous sheer fabric like this from opshops (you may need to rummage in the fabrics bin), and I have recently been going to one in North London that specialises in second hand indian saris and salwar kameez. They have whole room dedicated to indian shawls and scarfs, of every colour and mix of colours under the sun! Perfect for all my DIY projects. Sometimes you have to look in the strangest places for the best finds.
