Hi Shopaholic,
#1 This is my favorite, I think that the muted cropped sweater with that dress really shows off your figure. Love it. What about adding a necklace.
#2 I like how you made it edgy with the moto jacket and the long scarf is flattering. This is my second favorite. I think a pattern scarf would be even better with this, because it is a lot of black/dark color going on and the pink is big contrast.
#3 This one is my least fave, I think it is because that sweater IMHO, does not do you justice with your cute shape in that dress, compared to the first look. I am wondering if pink and black are the best combo? I'm definitely still learning about color combos but perhaps a deeper richer or more muted tone would work better? I'll look forward to hearing what the other ladies with more experienced eye than me have to say.
Again, I think necklaces would be a lot of fun with this versatile sheath dress. Please take my comments with a grain of salt because I'm really a newbie at this stuff! Thanks for sharing!
