Puff Sleeve Bow Blouse (Romwe, $44)
This is not a retailer that I am familiar with, but its pieces have been cropping up on Polyvore for awhile now. It appears to be a Chinese company. Le Blog de Sushi has a review of some of the pieces if you want particulars on shipping timelines and quality.
I ordered a blazer from Romwe a couple months back. The shipping takes forever, and the fit was super weird and small. I ordered my size according to their chart, and the sleeves were laughably narrow and the cut didnt allow for it to be closed. Also, while the designs are cute, I honestly don't think the quality is worth the price. I paid $60 for hot pink blazer on sale, and my H&M blazers that cost $35 are better quality. Sure I could return it, but they make you pay for the international shipping to do so. Just my experience, though!
