Sizing Secrets: For the Most Accurate Fit
-
Timing is Key: Measure your fingers in the evening when they tend to be slightly swollen and at their largest, ensuring a comfortable fit all day long.
-
Warm Hands Only: Avoid measuring immediately after being outdoors in cold weather, as frigid temperatures can temporarily reduce your finger size by up to half a size.
-
Wait for the Party: Skip measuring right after enjoying salty foods or alcoholic beverages, as both can cause your fingers to swell (and potentially result in ordering a size that is too large).
