lyn* - I agree - I've really been pushing myself to try on frames that are just the opposite of what I normally gravitate to, trying to "train my eye" and so on. But I've finally concluded that there are a limited number of shapes that suit my face shape - and that's fine by me!
Angie - Thank you so much for the clarification! You are so fortunate to be able to wear such a varied style of frames - and of course, skilled in picking such flattering shapes! It is good to know I'm not just wasting my money if I get similar shaped frames, as long as the color is distinctive.
tarzy - I agree - there are subtle differences in my current pair and the ones I'm looking to add - and that's enough for me - the overall shape is the same, and thus flattering on me.
bj111 & deb - how interesting! You are both so fortunate to have found so many different frames that are flattering on you. I just can't seem to break out of the rectangular frame mindset right now.
qfbrenda, Amy & Day Vies - your collective wisdom seems to echo Angie's advice. I feel more confident sticking somewhat close to the softened rectangular shape now, and looking for striking (but flattering) frame colors. Yay - thanks!
