Mandy Twinning Bundle – Adult & Kids Matching Jumpers Rainbow Stripes
Most of our knitwear designs are generous and intentionally oversized in fit.
If you like the oversized look go for your normal size, however if you prefer things a little neater we would suggest sizing down.
Here’s a size guide, for comparison:
X Small – UK 4-6
Small - UK 8-10
Medium - UK 12-16
Large – UK 18-22
