I’ve just got a Uniqlo jumpsuit in the sale and I really like it. The only problem is that it has a long zip that reaches way down to my lower back - and to pull it down (to sit on the loo) requires it to be unzipped completely and then zipped back up. I can’t for the life of me work out how to do this independently - are there any tips, tricks or magic tech I could use? The material is a bit unyielding with no stretch so I can’t just wriggle out of it
