Comic-on Talk

Hi, again. I don't usually do talkies like this, I just needed to talk. So, this February 15-16, I'm going to a comic-on, anime fest thing. And I really wanted to go in a cosplay, cuz I've never cosplayed before and I've never been to a comic-on. I decided I would either go as Asui or Uraraka from My Hero Academia, because 1. I have the same hairstyle as Uraraka (I'm female, but trans. My pronouns are he/him) and 2. Asui is my fav. I found a cosplay at a decent price of Asui thought, "K, I'll go in this cosplay" I showed my mom (I'm a teen) and asked if I could go in this cosplay. She said sure, and I got my hopes way up. Now, it's February 2nd, and I don't have my cosplay. Guess why. I asked my mom about it and ya know what she said? She said "I'm not getting it" WTF!! Look, it's not a big deal, I'm not looking for pity or attention, idrc, I'm just upset. So, I'm looking for a cosplay I can make, cuz my mom said she's not buying me a cosplay and that I can make one. IT'S NOT THAT EASY. I've spent hours looking on Google for an easy cosplay to make, I can't find any! So if you guys have any cosplay ideas that I can easily make, plz let me know. So yeah, thx guys. K bye (Don't use the voice or I will nuke your house)
