The crop top has been cropping up everywhere these days.. see what I did there ;))
I recently got a pair of pants from Missguided (post coming soon), and I was pleasantly surprised by the quality.
As far as black goes, it's not necessary to always get a matching set, black goes together easily.
I made my top from an old tube top i don't wear, which is also a great idea. Very limited sewing skill is necessary, just cut the top, and use a needle and thread to make a blind hem. Blind hemming is a technique where the needle is used to pull up a tiny stitch so the thread isn't seen on the face of the garment. (more here)
Have a great weekend everybody!
