The fabric to me looks like some tye die effect, but let's see what others have to say. Also not sure about dating. It could be vintage, or it could be newer - it definitely has that kind of "hippie vibe" and I know some shops around here that would sell something like this still.
The way it is made looks homemade though - especially those zig zag stitches... it has a boutique label though. Might be someone working from home selling her stuff in a small boutique.
What I can tell you is that I am almost certain that it is from Switzerland, more correctly from Basel. Bâle is the French name for Basel, and I think what you say it says on the second label (can you show a picture of that too please?) that's what it refers to, the city, and not a family name. According to the label, the boutique's name is "Zur Arve AG" - arve is the name of a certain type of pine tree that grows in the Alps - all over alpine regions in Europe, but it is in Switzerland only that we call it by that name. In Germany and Austria they use a different kind of name for the same tree. AG just means public company - sounds rather grand for a boutique, but who knows. In der Steinen seems to refer to the old town part of Basel called Steinenvorstadt - that's what Google tells me when I search for that. It seems this is a terms the locals use. I am Swiss, but not from Basel, and not too familiar with their specialties, but they do have a very distinctive dialect and some peculiar words. Komödie is probably meant in the sense of a theatre - maybe the shop was next to one or something like that. There is one very famous theater that does comedy in that part of Basel, but I would have thought if that was meant, they would have used the actual name of the theatre - because everybody knows it.
All that being said - I did various searches for the boutique, for the name Creations Catherine etc. - it all turned up nothing. Couldn't find anything in the current phone directory either, so all of that would point to this being something older...
