This will be a main staple in my autumn/winter/spring wardrobe The fit is perfect , the quality is amazing and the fabric is so soft Pls bring more out like this
This long sleeve is the perfect mid weight fabric for the cooler months. Can wear on its own or layer with another jumper/jacket. True oversized fit
Love this jumper. Good quality. Large sizing.
Super comfy and great quality fabric. Quite oversized - recommend sizing down
The quality of this top is great. I never expected the fabric to be so thick but that's what you want coming into winter.
Great quality product. Looks good. It is oversized. I got a size large, could do with a size medium but it doesn’t look bad. Looks great. Has great shape.
Love so much. Comfort and goes with everything.
Love it but it’s very oversized so keep that in mind when ordering
Super lightweight and cool, nice to throw on when you don’t want a full on jumper but it’s also too cold for just a T-shirt.
Love the shirt great for walks and to throw on if you need to step out of the house. It is very long and oversized so size down 1 or to sizes to your normal size
