Thank you all for your replies. This is really interesting!
It seems that many of us duplicate basics (undies, camisoles, etc.) in the exact same colour or a different one. (Angie, Suntiger, Chris, Jenni, Kate, Joy, and more. Waving to my team mates here. The reasons seem to be: we like matching undies (raises hand) and we are hard to fit (raises hand, at least where bras are concerned) and we dislike shopping for these items, considering it a bore and a chore compared to shopping for other stuff (ditto).
When it comes to clothing, some of you admit to (or revel in) being uniform dressers and suggest that as the reason you duplicate. Which makes sense. Either because you don't like shopping, or you like efficiency, or you like to limit your silhouettes within a season (or always), buying up dupes makes a lot of sense.
What I notice about duplication is that it can offer a certain amount of comfort. At the same time, it can also facilitate gentle experimentation in those of us who are perhaps less adventurous.
Particularly as silhouettes shift -- when you find a new item that works really well for you, if you see it again in a colour or pattern you also like, that can promise both a certain amount of safety (this one fit and looked good so that one will as well) and a certain amount of experimentation or fun (oooh, I've been looking for a top in that shade for ages...or oooh, that will work with my other pants, etc.)
Peri, thank you for your kind comment. I think of a truly creative dresser as someone like our Jaime, who dresses briliantly from thrift, or Jonesy, who has an amazing hi-low style, or Brooklyn, who goes the distance to boss her clothes around and who plans ahead in terms of what she is trying to accomplish. I think I might be on my way to that as I continue to refine my own style, but I'm not really there yet. I am still more of a "what's available at retail" that generally fits my style parameters kind of dresser. (I'm not trying to put myself down here; I like my wardrobe and like how I wear my clothes! Just saying it's a process or maybe a creative journey and I'm still in the beginning stages (10 years into starting to put effort into it, LOL.)
Carla -- yes, what is up with all our recent dupes?? Maybe it is because we needed a major refresh this year? From the photos, it looks to me as if you have duplicated core essentials, either in another of your core neutrals or in one of your key accent colours (so one becomes a kind of completer piece). I've done something similar -- I buy in two key neutrals (the sweaters, the pants, the footwear). Or I buy and rebuy a style that just plain works really well. I mean, I go in with the goal to dress as a garçon -- how can I resist a garçonne shirt when I adore button front shirts anyway, when I haven't updated my capsule of shirts in a long time, and when I love love love the cut of this one? Anyway. All of this makes sense because although my wardrobe is nowhere near as tight as yours, I think we go about building our closet in a similar way and we share a classic style gene. And, quite crucially, we are at a point where we both know our style pretty well.
Helena, it makes perfect sense to me that you might duplicate less as you dip your toes into a style shift/ new silhouettes. It goes with your personality and your approach -- you've been cautious and don't want to overspend on dupes until you feel more secure. I think in most cases, your dupes work really well for you.
cat2 "the same cargoes with the same top" -- yes, this is the fear, right? I learned pretty early on in my WFH life that I get more bored by wearing the same silhouette all the time than I do by wearing the same colours all the time (much as I love colour). So I need options in silhouette. This does lead to a larger wardrobe, though, because you often need different tops to work with different bottoms. Sigh.
Star, you make a really good point about second hand shopping. I intend to shop more second hand this year myself, but I realize it is because I may be looking more for completer or statement items. Which makes it easier. I hope it's not cheating!
Chris, it makes perfect sense that you would duplicate when you find something that fits and that you like. There are risks, too, though -- at least fo me -- the main one being a sense of boredom with what you have.
Dee, I'm not surprised you duplicate -- I think your duplication mirrors mine and Carla's, because we start from similar style sensibilities.
Suntiger -- wow, you have some beautiful dupes! I'm not surprised you bought the exact same MK bag. As cat2 said, function in purses is so key and when you find a shape and a functionality that fits your style -- grab it!
Olive Green, you raise a really good point -- it really only makes sense to duplicate if you know your style and your needs extremely well. Sometimes maybe we get caught up in this -- if we have duplicated well in the past, but forget that we are now living a different lifestyle or in a different climate, we might get fooled.
Sal, you are right -- it will be interesting to see if I continue to duplicate as much I suspect not, for the next while.
Pirouette, that is so interesting -- the fear that you might not find what you need in future. I wonder where that is coming from? But it is great that you feel you always have something you can wear and you can pack easily, etc. A wardrobe that works for you!
Jenni, it makes sense that Roberta's comment about thanking the item would resonate for you. You used to have trouble letting go of items but now you have figured out a way to do that and feel less bad about it.
