In my opinion,董娜is better.Because 董娜's pinyin is DongNa,it's the same as your name.

Yes, Donna = 唐娜. 唐娜 is a beautiful Chinese name. Hope you like it.

In my opinion, 冬娜 is better. 冬means "winter", 娜shows that you are a girl. And I think this name can give others the impression of a beautiful and slim girl. Because you don't have real Chinese family name, so 董 is not proper for you。

It is of Italian origin, and its meaning is "lady". The original meaning is closer to "lady of the home". A title of respect, equivalent to Don for men. 和中文名“娜”的意思差不多，表示是个女孩。 或者可以叫：唐淑贤 唐淑静，听起来是个贤惠的居家女人（ "lady of the home"）。

董娜 i think so
