It’s so bad that my fiancée has some bras that say she’s a B cup and others that says she’s a D cup. In order to go bra shopping, you have to actually try them on to find out if they fit.
If I had to try on underwear to see if they fit, I might not bother with underwear at all!
It used to be that any DC skating shoe size 12 for me. Could just pick a model and leave the store. Then they became a fashion brand rather than a skateboard brand and suddenly it was made for tiny model feet.
A got older with an older body I just get the Bondi8 for summer and Kaha for winter as HOKA does wide and quarter sizes.
