Honkai Star Rail Herta Cosplay Costume

Weird lenght. Not fitting and quite cheap material as well. A lot of custumization to do, and it's a blessing I at least know how to sew to make it fit.
Also pls learn to make the sizing right. For 100$ I was hoping to have at least the minimum good fitting if not a great quality material.
For the improvement to make :
- the lenght of the skirt / dress (should be quite short but is actually longer than my knee.
- Make a skirt & a shirt instead of a random rectangle cut out with no shape for the top part of the dress
- 2XL means the buyer should have some boobs, but I cannot fit without weirdly compressing mine

Overwise, the accessories are cuter than expected, and the details are mostly presents (except of the purple arm part) so the globalcosplay is ok. Just disappointed with the weird sizing.
