Grandma's dress?? help!

I can't decide what colour to do grandma's clothing. She is a ninja so I thought she would be in black, but that gives me a world of hurt inking it in if I still want the arms to show.

So I was in the Dutch NaNo chat yesterday, where Lenihan gave me the marvellous idea to give her a flower dress, which will make her look more grand-motherish, despite her ninja outfit.

So I made a few pattern stamps myself, and I would like your opinion. Which grandma do you like best? The darker patterns are more 'ninja' suitable, but the lighter ones show the arms better. I think the Delft Blue pattern is hilarious but that may be too Dutch. Pattern nr 5 I will need to adapt if I choose it because it shows a too obvious pattern-rim (hope that is the right word) and that may proof to be quiet a challenge..

The other MC's are: bright red for me, grey for Zowie en light grey (metal) en brown (wood) for Shovel and Picky. The dwarfs are purple.

Here are grandma's possible dresses:

EDITED TO ADD: Apparently it wasn't Lenihan, or only Lenihan that gave me the grandma-flower-dress idea, but I owe my thanks first and foremost to BrokenWings for it! So thank you BW, and sorry I got confused about who said what in chat! :-D
