He called me from the shop laughing: "Yeah, I have the box with the shirt but it costs 600 bucks and I don't have 600 bucks even if I give them all of my cash and use all of my balance on the card. It still won't be enough". It turned out to be some hand-made designer modern take on an ie (when I asked him to pick it up I assumed it was just a regular 20 bucks ie). I asked him to give the phone to the shop assistant who turned out to be the owner, she sounded like she knew Helga well and was more than happy to let us take the shirt and pay next week when I will be in the city again. She was super friendly and asked me not to worry about it all.
So this is the 600 bucks Moldovan peasant shirt that Helga will wear to the party we are going to this Sunday (this isn't Helga of course):

I'll also be wearing a traditional shirt but mine is 30 bucks. And mine is a real one and is OTT colourful af as they are supposed to be.
