Well, even though I figured out what my style persona is, I still like to try new looks. That's what fashion is all about--it's a dynamic process. You don't want to get stuck with one look for the rest of your life. I see different styles and I really like them and want to try them out. Sometimes it works, like when I tried Parisian Chic:

and RATE (I had to LOL at what you said in your OP, this actually was my attempt to RATE Kate Spade!)

and sometimes it doesn't (I still am having trouble cracking the UWP nut, with laughable results--see my internal commentary at the end of the thread):

but no matter what, I am having fun trying it out!
I know what you mean, I am very impressionable and whenever I see a cool look on someone else, I always want to try it. But that's OK because I still know what my main style persona is and I mostly stick to it. In my Euro Chic attempt, Claire jokingly said that I am not "allowed" to have two different style personas. But Rae pointed out that my take on Parisian Chic was still very me, with the fitted waist and bright colors, unlike the looser fit and neutral colors typical of that style. And even my attempt at RATE was still pretty polished and not truly RATE, according to Angie. So even when you try a style element that's very different from your typical persona, you can still incorporate it into your style--filter it through your style lens. It's fun to have some dramatic tension from the juxtaposition of different styles...more fun (and less costumey, especially if you're into retro styles) than dressing head to toe in one particular look.
I absolutely think you can pull off various styles and make them your own. I think you should try the mod look if you like it! I really enjoy your WIW's and look forward to seeing you develop your style persona further!
