Gah! I thought I had fixed that weird corner! Thanks for reminding me- I updated the image to what I have now, but to save you from scrolling up, I'll just post it again.
Before edit
I'm still trying out some things with pixel clothing tutorials I've found, but I definitely know I need practice. Thanks so much for helping me, it means a lot.
**Edit: Fixed the pixels for the right side neckline on the 'cup' so it didn't look funny.
