I have a similar version of this apron which I have used for a number of years, (and which I think I originally got through Lee Valley.) Mine however differs in several important respects:
1) Mine has a rigid semi-circular support in the top rim which holds the top open. Note how the current model from Lee Valley is soft, requiring the operator to hold it open with his other hand to deposit material.
2) Mine is quite a bit deeper, (so it will hold more before needing to be emptied). (But I have no problem with the weight of a full basket being too much)
3) Mine came with Velcro fasteners to hold the tail of the bag up. The L-V one has a much superior system consisting of cords in jam cleats. I modified mine by getting a sail maker to install "turn grommets", (oval catches that go through a matching grommet, and then turn 90 degrees to lock them). These work fairly well, but occasionally unlock themselves.
4) Mine has an ingenious system of tapes to support it, while the L-V has a much wider harness arrangement. The L-V one looks more functional. BUT, the narrower tapes on mine are both simpler, and wholly satisfactory functionally and comfort-wise.
Mine has a label with remarkably full and detailed information as to manufacture. It was made by AES Global in Lévis, Quebec. I contacted them, and they no longer make these aprons. (They are, however, a source for all manner of biopesticides like BTK, Beuvaria and nematodes if you are looking for same). They referred me to Derco Horticulture, in L'Ancien Lorette, QC. They at first denied having any remaining stock of the aprons made by AES Global, but when I found it in their catalogue, acknowledged that they did in fact have them, (Cat # 32-313).
My personal take is that the old AES aprons are considerably superior to what Lee valley is now selling, and as long as you are willing to improve the fixation of the bottom of the apron, I would send your good wife off to Derco rather than Lee Valley. (It is a little unclear to me whether Derco considers themselves a retail operation or a wholesaler. Before heading off to Ancien Lorette, (wherever that might be), it might be wise to contact their HQ in St. Germain de Grantham, (again, wherever this may be in Quebec).
