Lanvin White Neon Runners
Go a size down from your normal size as these fit big!
Kids Lanvin White Spider T-Shirt
Lanvin Burgundy Embroidered Spider Crewneck
Medium - 22.5" PTP
Large - 23.5" PTP
I would recommend going a size down as these fit generous!
*PTP is the measurement from one arm pit to the other.
If unsure on the fit, compare measurements to another item you have that fits.
