My wife cosplays Isabelle, so yeah, that's a given. My personal Animal Crossing waifu is actually Sable, the eldest Able Sister. In New Horizons (Switch), she's the one on the sewing machine. When you first meet her, she rudely says "other hedgehog, please," and proceeds to ignore you, but if you keep talking to her, you become the highlight of her day. She's a nasty old lady when you first meet her, she knows what she needs and wants, and she does not give kindness freely. But if you get to know her, you will become her favourite person. (She also has history with Tom, so there's that, too.) (I cosplay Tom, so it works with both of them. I'm not saying Tom cheats on Isabelle with his ex, I'm just saying he has an open door policy, and if you know one NSFW fact about tanukis, it's probably the same one I know, so you know one woman can't take care of him alone.)

I can also say that this is her New Leaf outfit (and possibly prior games). I think she will still wear the green top sometimes, but mostly it's salmon, and the design matches Tom's shirt, with the Nook leaves.
