Nice outfits! I struggle with trying to liven up my outfits too. I seem to have all but eliminated prints from my wardrobe for some reason and everything is looking so blah lately.
Not sure if it's your style but I would also try some shorter chunkier necklaces too - for example with outfit number one (which is fab by the way!) , you could try something like:

Target actually has a great costume jewelry selection and the prices are very affordable. I am also seeing alot of print scarves in spring colors in stores like Target, Marshalls etc.
I'm by far not a vest expert so maybe someone else would disagree but something about outfit number two seems a little off to me. I'm not sure if the shirt is maybe too long or the vest a little too snug or short. You could try the necklace from outfit three with this look - a longer necklace seems just the thing.
I really like your top from outfit three and I think you might liven it up with a different color bottom (although the bottom that you are wearing is a great fit & PPL). It looks a little boring to me because it is so monochromatic. Maybe try it with black pants, dark denim or even ivory or cream pants. Of course skirts & boots would be great too!
