why mary just use one tiara?
Do you mean Marie? Or are you talking about Mosh?
Marie has two tiaras-the big floral one, and a smaller floral one. Mary only has three tiaras, which is quite a small amount considering that she's a crown princess. The DRF doesn't have a lot of tiaras, and Marge is very stingy with lending them out to her daughters-in-law. It is kind of funny that the one that Marie was given (or lent for the long term) by Marge is much bigger and nicer than that terribly dinky tiara that Marge gave to Mares for her wedding. If it wasn't for Ingrid leaving Fred the ruby tiara, then Mary would only have that small tiara and the Midnight Tiara.
Mary has 4 tiaras, I think. The wedding gift horror, the ruby tiara, the midnight tiara and the one she purchased at an auction (an ugly one). i love very much the midnight tiara, and the way she altered the ruby tiara. I like it more the way it is now.
