I think this is entirely up to you. People wear bright Spring colors like hot pinks, corals, to bright purples. But I personally believe a more muted soft pastel palette will be popular this Spring and Summer.
This dress from Inherit Co. has the beautiful, muted floral print in cream and light pink.
Also, a neutral palette is always nice for Easter because so many choose to take family pictures for the Spring during Easter season. Neutral palettes make for the best pictures that will look good for a while in spite of passing fashion trends.
I hope this helps you as you decide what you should buy for the Spring season, and as you pick out the perfect Easter outfit.
