First of all, as I think I missed your "presentation post", Welcome from Oslo.

Secondly, and to the more pressing issue at hand, the tartans.. This is not an easy choice, and it is truly one which you alone can make. The Romsdal tartan is quite lovely and you would certainly look smashing in it on events such as 17 May where you might find yourself alongside men and women clad in the Romsdalsbunad where, as you have illustrated, the tartan is splendidly put to use. It would certainly give the more spectacular effect of the two tartans on such occasions. Not an easy choice at all, but whichever way you go, you will always have the option (finances allowing) to get the other one at a later time..
