I'll keep it as short as possible.

Recently, my cousin got engaged and is planning to wed next month. He gave our family money to buy dress for the wedding. Let's say it's around 600 dollars to split up against 5 family members.

My sister(21F) bought two expensive dresses for the wedding . She said she initially planned to buy one but somehow ended up buying two as she really liked both. My brother (14M) got himself a really good suit ( not expensive as my sister's but still pretty good) My parents also got themselves nice dresses and I(19F) was the last one . Turns out every single dollar is spent.

Before you ask , why I didn't buy soon , I thought we'll all together but my sister and brother went shopping one day ( I had an internship that day ) My parents also went after that.

When I asked about it, my parents just told me to borrow one of my sister's old dress . I simply refused and asked them to buy me a new one . Then they told me if I buy new expensive dress instead of wearing my sister's , I won't be probably buying clothes for next couple of months ,which I can't because I'll be needing casual clothes for wearing at home and for going out .

Let me tell you what , being a middle child sucks. All my life , I've been either using my sister's or buying the cheap ones compared to my sister.( Not just clothes , literally everything) . Even my college fund was used for my sister, just because I was able to secure a 95% scholarship( I'm a really good student). They did ask me before taking the Money out , I said okay because it happens every time. All the money they've saved for me or they gave me has been taken back by parents or sister and only paid back a little so far.

So AITA?
