I love the look of the Wunder Train Long Sleeve Crop - but not for the insanely high price. I found this "dupe" on Amazon for $20 CAD. I love the colour and the material is a plan cotton-feel. I sized up to a medium in this top because I didn't want it to be too cropped. I normally wear a size 4 in Lululemon tops.
I will likely be purchasing some other colours (they have a ton of colours!). I've been looking for a decent long sleeve crop top for a while now, and I think these will work!
