Vintage sizing is very different from modern day sizing systems.

We do our best to accurately convert vintage sizes to reflect modern day sizing.

However, we recommend going by the measurements provided in item descriptions as there is much variance.

Please email us with questions or for measurements that are not found in the item descriptions. 

The chart below is a good starting point for size conversions.
