The companies you've mentioned are American ones, suggesting that you're in the USA. This website is UK-based, so it's unlikely that anyone here will have ever seen a catalogue from Garnet Hill or Soft Surroundings (or, indeed, even have heard of those businesses). You might stand a better chance of getting a useful answer if you post on a US-based website, such as Quora (or possibly Stack Exchange).
Old Sears catalogues turn up on eBay UK though (despite Sears being an American firm and largely unknown here in the UK), so I would expect similar items to be listed on eBay USA. Perhaps you need to be looking for catalogues where only a section of the contents is devoted to fashion, rather than solely for fashion-specific ones? (Spiegel? Montgomery Ward?).
It might also be worth contacting the Ephemera Society of America, as their members are likely to be aware of the best sources for old catalogues:

I'm (obviously!) fumbling a bit in the dark here but I've just found an eBay USA link that seems to include several catalogues which might possibly be of interest to you, so I'll throw it into the mix:

Good luck with your hunt!
