It's not a grammatical error. More of a joke, per sé, likely more of a reference.
There's an old tradition (in the UK, likely other places that were colonised by Britain) of keeping, curing (with spirits) and these days freezing the top tier of a wedding cake to be eaten at the Christening of the couple's first (or later) child.
A recent example:

There's also the tradition of making Christening gowns out of part of the wedding dress, etc.
Back in the 18th century, here in the 'Colonies', it was a tradition that a person be buried in their underthings worn at their wedding. And no, that's not what we call underwear, per se, since they didn't wear any. Rather, what served as such was the shirt for the men and the shift for the women. Underwear, more like we know it, came along a tad later in the early 19th century. All I can say is, it's a good thing linen lasts. The Bride's cake was also never eaten by the wedding guests, but rather stored in a tin soaked in brandy and brought out at each anniversary. Instead, the guests ate the Groom's Cake. We rarely see that cake anymore.
