Conversion Chart
Many of our clothes have international clothing sizes, particularly EU sizes (e.g., 70 in EU is 6M in US). US sizes are typically based on age meanwhile European clothing sizes are based on height. Hopefully these conversion charts are helpful (though we have converted sizes on our site all to standard US so you shouldn't need these charts when selecting clothing from SoooSweet.com).
Note: these size conversions are merely approximations as apparel companies tend to make clothes based on their own version of standard sizing.
