I love my polka dot dress from Ann Taylor. I'm in love since I first saw it on-line! It's classic, it will be trendy forever and I believe you can make tons of cute outfits with it. Today I decided to go bright and wild and combine spring-grass-green with fuchsia. Why not? Usually if you can find this combination of colors in nature it will look good in your interior or outfit. I was thinking spring flower field and dark lake water.
If for some reason you do not want to accent your waist, but you purchased a dress like mine, just do not wear contrast belt, make it matching color.
If I has not already picked up a bright pink purse matching my belt, I would put on my fuchsia shoes... But I'm wearing matching color navy blue for another reason: they make me look a bit taller! Contrast shoes (even same heel high) will not give extra couple inches! :)
