This is a bunad, in size 4-7, purchased at Oslo Husfilden in 1984 for my daughter. She didn't wear it much, certainly not once a year... until she grew out of it. It was a sentimental/impulse purchase as we were leaving Norway. Actually, it was my husband's idea, and I thought at first it was just silly, but the longer I have it, the happier I am! Especially now that my granddaughter who is half Norwegian can get lots of use out of it.
lots= once a year or more.
It is very plain compared to most "bunads". Others have beads, embroidery, shawls, capes, and woven braid trim, and are longer. I think it's lovely, and with her Norwegian grandmother's jewellery, it's good enough to get a special report in the local newspaper.
How does it fit a 4 year old and a 7 year old? It is heavily hemmed, and the side and shoulder seams are overlapped so they can be opened up. It should be good for one more year!
