Re: Are these outdated ??
You might get away with them, but chances are high that people will follow you with torch fires if you do waer these dresses 
Please, wear whatever you want. These dresses are perfectly fine to wear. They are not outdated.
Nobody cares what you wear anyways, only lifeless make-up kits do.
Re: Are these outdated ??
^haha, yeah also believe that you should wear what you like and i despise people who always make remarks on who's wearing what. my niece who's 20, wore my sister's old outfit at an engagement ceremony, which is basically like the green one except that it's white and has some nice details in it, and she looked very pretty and not outdated at all. i gave away the pink one because i didn't like it anyways and i actually realised i have some very nice outfits in my suitcase.
i guess it's fine to wear an old outfit as long as you carry it well and you will still look elegant if you do the rest right, make up and jewellry wise. last time i saw some gals wearing very nice dresses but they either had no make up at all or had wayyy too much so you gotta balance everything
