I don’t think you can blame Lovehoney when they’re just quoting the brand’s own size chart… however stupid that size band seems! The Vixen bra sets (both the Black Striped Mesh and Red Fishnet) are made by Fantasy, they are not a Lovehoney set, and their own site has the same weird sizing. @Kitty-Cat01 raised the subject here about the Red Fishnet set as a possible typo, sadly, it’s not a typo but an issue I’m afraid you’ll have to raise with Fantasy rather than Lovehoney.
@Kitty-Cat01 , did you get the set in the end? If so, any insights into the odd sizing brackets Fantasy use with their Vixen sets?
