Ladies, it’s time to invest in some Pilates classes because come warm weather you might find yourself wanting to don some midriff baring ensembles. Seen all over the fashion week runways and already a favorite amongst Hollywood starlets, crop tops are making a big comeback. But these aren’t your 90’s belly-ring baring styles that were so popular with the teen stars of the time. Crop tops have evolved – and what a welcome evolution it is.

Midsections are now tastefully on display everywhere. But how do you keep it classy? There are a few simple rules to getting this trend just right.

Rule #1 – Know what makes you comfortable. If you’re on the shy side opt for a high-waisted skirt or pants to keep your crop top from showing too much skin. Check out Olivia Wilde’s outfit.

Rule #2 – This season’s crop tops are about being classy. So trade in your tight mini-skirt and go with something a little more refined. Selena Gomez’s outfit oozes sexy, yet she still looks quite the lady.

Rule #3 – Dare to be different! Kim Kardashian isn’t afraid to elevate her crop tops to evening wear.

Rule #4 – Wear lower-waisted bottoms with longer crop tops, and higher-waisted ones with shorter. Vanessa Hudgens and Beyonce rock very different looks, yet both are still impeccably styled.

Now that you’ve got the tricks of the crop top trade, the only question left to ask is do you dare to go bare?
