My partner tried to order me an Oodie last Christmas. We didn't have the greatest experience with them to be honest. They gave us an estimate dispatch and arrival date and then we kept getting email updates telling us that the date had been changed further along- I think we ordered it in early November and then they ended up telling us it would be arriving late February! On doing a bit of social media snooping it seems that a lot of people had the same problem and some people had been waiting months to receive their order; They might've sorted it out by now, but if you do order one, keep an eye on the dispatch dates.
We ended up cancelling, getting a refund and I now have the very warm and cosy oversized Sherpa hoodie from Sienna on amazon.
