Why, pop on her fancy diving gear, hop in the deep blue briny and get one for herself, of course. It would have totally complimented that outfit.
We actually got 10 of these in a dive over Christmas. They look awful, but are delicious when tenderised and done on the barbie in butter and garlic. Its was real treat as they are getting fished out in the waters at Yorkes because there is such high demand for them in asian markets.
FYI, no purse was actually borne of this underwater adventure. I think the shells got turned into ashtrays.
