Her chic collection has handmade, limited-edition pieces that are a little pricey, but they're made with quality materials.
Out of the few pieces in the Couture Collection, I think that pink Merino Wool Corset Jacket is my favorite piece. This collection can only be bought online here.
Nicki Minaj also has the Classic Collection which has classic, basic pieces.
No shade, but most of these pieces can be found at any Instagram boutique. I think her Classic Collection will do well though because it brings a little edge and sexiness to the clothing options that are available at Kmart.
