AITA for not letting my sister wear my dress?

I (17f) just got into a fight with my sister (21f) over my dress.

I bought it only recently and have not worn it yet, since I haven’t had a good opportunity for it. It even still has the tag on.

But then someone else starts eyeing the new dress…

Well my sister is going to an opera house with her boyfriend (28m) this weekend and is searching around the house for a dress to wear.

Even though she owns plenty of fancier dresses, she remembered mine and despite my clear annoyance, tried it on.

Then the conflict escalated.

She really liked it and wanted to wear it.

I told her no, since I personally have not worn it yet and it is the only fancy dress I own. Because of my answer she called me a brat and an ***hole.

I feel like I could’ve been nicer and just lent her the dress, but still, I got very attached to it and would hate it if my sister had worn it before me, especially since I bought it with my own money.

She has a job while I do not, so I don’t have any reliable source of income.

AITA?

She should at least be able to wear her new dress at least once while it’s new, right?

What did Reddit have to say?

This user is on the dress owner’s side.

It’s not just about the dress!

She’s the older sister, so she should act like it!

With tensions high and feelings hurt, she wonders if it was worth standing her ground.

This sisterly relationship is hanging on by a thread.
