(Very belatedly. Apologies for thread necromancy, but I didn't feel a new thread was warranted.)

     Well, I said that was the right story, but later I realized that, no, it wasn't the one I'd been thinking of. I've been trying to find the right one again lately, and I still can't.
     For additional context, here's what else I can remember about the story in question:

• The gypsy or fortune teller lady whom the main character meets works out of a tent that she's set up at the fall festival she's part of.
• The main character doesn't really realize their transformation until later, when they get home afterwards. Their sister or mom notices that their cleavage looks real, then the latter has them strip and take their costume off to check, potential embarrassment disregarded entirely.
• As noted in the last bullet point, the main character has a sister.
• His mom might be a single mother? The dad might have passed away some time before the story began, perhaps?
• I remember the main character being at least mildly distressed at their predicament of getting stuck as a girl and a bit reluctant to adjust too quickly, but they were also resigned to it in that they knew they just had to grit their teeth and bear it.
• The rest of the plot was sweet and/or sentimental.
• Other than the initial transformation impetus, the story's setting was quite mundane, otherwise resembling our real world.
• The story was multiple chapters, as I recall if I do correctly, but wasn't terribly long, either.

     Any help finding this story from anyone would be greatly appreciated. I enjoyed it; it was cute. I'd kind of really like to read it again. Not being able to locate it is frustrating.
     I know it isn't either of:

• The Witch's Tarot by Nick B or
• A Trick…or a Treat? by Zoe Taylor

I've read those again recently.
