Parka coat from Hollister in an XXL which is a generous size 18.
Hollister has sold out in the larger sizes of this coat, and it's not surprising because this coat is gorgeous. Faux fur lined and with a faux fur trim on the hood it has a stand up collar inside the hood so your neck is warm even with the hood down. Cuff up the sleeves too so the cold air doesn't get up your arms.
I had assumed Hollister sizes would be tight so ordered up, and have found they're not at all. This is a really true to size size 18. Gorgeous coat grab a bargain! £109 new!
