I posted some "possible" look-alikes (more of joke ones than actual) in a separate thread by mistake, so here's another one to redeem myself...
I work at a clothing store, and over the summer they put up huge posters of models in various outfits. One of them looked exactly like Tatiana!! It was so weird, it was like I was seeing her in modern clothes when I went to work every day! I tried to find the picture online because I didn't want to seem like a weirdo by taking a picture of the poster, and I found the same girl in a different pose. She doesn't resemble her as much in this one, but you can still see it:
There are a few people who went to my high school that I also think resemble Romanovs. I wouldn't post their pictures here without their permission, but one of my friends looks like Olga Alexandrovna, and a girl from my class looked like Tatiana. I'm actually surprised she never noticed, since we actually did a whole unit on OTMA in history class! I guess our teacher just didn't show us enough pictures.
Also, as much as I hate to say it, certain pictures of Anastasia remind me of Emily Osment from Hannah Montana...
