How to customise a plain thrifted blazer Charity shops and thirft stores are full of them: plain, boring blazers in all shapes and colours. With all things 80s making a huge comeback right now, including shoulder-padded jackets, it’s time to get customising. Stylist Isabella Buckland shows you how to! This is so easy! Find yourself a women’s blazer. I found this black, very boring one in a charity shop for about £3.50 Firstly change the buttons. There was only one button on mine so I replaced it with a ritzy gold one. Even MY sewing capabilities can handle a button.
