Dear SYSter, I LOVE hearing your story about the power of accessories! Yes, they truly are amazing (as shown in this week's article). They add so much to basic outfits-that you really don't need a large wardrobe with the addition of a clever accessory or two. I love how you explained what you wore and the accessories you added-how the accessories made your look different each day (and got you compliments).
Based on your body type and being petite, I would avoid a long lariat or Y necklace. (you can try one on in a store and see) I think it will probably bring attention to your shorter height and bring attention to your bust. To answer your pin (brooch) question....Yes, yes, yes! Wear them. Add them to a blazer, on a cardigan, to hold a sweater closed, on a wool cap, knit cap, added to a long scarf wrapped around your neck, etc...I try to add a pin when I can because they are so under worn they bring a fun, unique look. If you wear one on a blazer-your necklace, if you wear one, should be very simple and small. One accessory needs to be the star. Hope that helps.
Love, Leslie MSP
