If you have ever tried on wedding gowns and wondered why the number on the tag does not match the size you usually wear, you are not alone. Wedding dress sizes follow a completely different system from everyday clothing. At Roselily Bridal in Richland WA, we explain this to nearly every bride who walks through our doors because understanding bridal sizing makes the entire shopping experience feel so much more comfortable and confident.
Why Bridal Sizes Do Not Match Street Sizes
Most wedding gowns are based on old school patternmaking standards many of which date back to European sizing from the mid twentieth century. These traditional systems never evolved alongside modern ready to wear clothing which means bridal sizes tend to run much smaller on the tag even though the dresses themselves are not actually smaller.
For example, a bride who typically wears a street size 12 may need a bridal size 18. This is completely normal.
Wedding gowns also include structured elements like boning layering and built in support to create a precise silhouette. Because of that designers rely on detailed measurements instead of the flexible vanity sized approach of todays everyday clothing.
What This Means for You as a Roselily Bride
Expect to Size Up
Sizing up by two to three sizes sometimes more is standard when trying on bridal gowns. It does not reflect your body or your everyday size it is simply how bridal sizing works.
Each Designer Fits Differently
Just like ready to wear brands vary every bridal designer uses their own chart. A size 10 in one collection may not fit the same as a size 10 in another.
We Carry Realistic Sample Sizes

Alterations Are Part of the Process
Almost every wedding dress no matter the size requires alterations. Tailoring ensures the gown fits your body perfectly.
A Little Bridal Sizing History
Traditional bridal sizing was created long before modern clothing standards existed. Designers stuck with those original pattern blocks because wedding dresses are more sculpted and structural than typical garments. Over the decades everyday clothing sizes changed but bridal patterns did not which led to the size gap brides notice today.
