DIY: sleeveless trench coat

so, i’ve had a trench coat lying around for a little while now and have been wondering what to do with it. i really loved the burberry studded ones they released for last spring but their retail price was around £12k which is completely insane. i also really loved the one from the photo above. i’ve been having a little think about what i was going to do and i feel like the sleeveless one would be more practical as the studs are a) expensive to buy b) time consuming to DIY and c) get caught on absolutely everything so would do my head in. i’ve got some free time before i go back to university so i think i might give this a go. and by ‘i’, i mean get my mother to stitch it for me. she’s good at all that kind of stuff
