Oh my god.
I found the perfect!! fabric for this skirt, waited until payday to put in an order for it and... it's sold out.
I have no idea where to go from here! Been searching high and low for another fabric, but no go. Is there perhaps a good way to do the floral design myself? I've never tried anything like that so I'm totally clueless right now.

Is it better to stick to an accurate shoe (heels) and be way taller than the character, or to wear flats and be closer in height?
Specifically pic related, I'm already 5'5 and accurate shoes would make me like 5'7 which is much taller than Nico. Would it be weird to wear flats instead?
