We run true to size, not big, not small. We advise ordering the size you order in other US brands. Our size chart is for general reference only, as it's impossible to have one size chart fit the hundreds of styles we make. If for some reason an items runs small or large, we will very clearly state such, in bold letters next to the product, so you have the best chance of getting the right fit!
