Skirt for Hanna

I made myself a skirt in this fabric earlier and had a remant left and asked my niece if she wanted a skirt in it and since she loves pink and purple... I used a very simple skirt and did a fold on the front piece inspired from a skirt I made earlier from an Onionpattern. Not beeing able to try it on I sewed the sideseams after the waist to simplify alteration
Her birthdayparty is tomorrow, and I known this for a while so why do I have to do this in the last minute?
