I just found the most beautiful velvet top at the Gap. It's a casual kimono-sleeve tee that drapes beautifully, made of a rayon/silk blend. It's trendy and super high quality -- it could easily come from Rag & Bone or the like. The cut is really loose, so it won't be everyone's cup of tea. But it reminds me of the Elizabeth Suzann silk tee that people love, as worn by Caroline at Unfancy: http://www.un-fancy.com/outfit.....four-ways/
I ordered it online after trying it in the store because there's a better discount online (40% off today). I do want to take photos once it arrives to make sure it's not too overwhelming. XS was definitely the right size for me. With my short arms, I might shorten the sleeves an inch or so.
I think I could wear it with faded jeans to work and not feel too fancy. I was wearing high waist vintage-y gray jeans (in finds for reference) and it was a great combo.
Click through to watch the model walking, because the photos are all pretty meh.
Edit: the top arrived, and I wore it to a party last night with my new (used) high waist jeans and my new Paul Green shoes. It's almost overwhelming on me but my boyfriend really liked it, which is a good indicator that it moves enough in person to not look totally shapeless. The velvet is so soft - 80% rayon, 20% silk. I added some photos of yesterday's outfit, though the sunlight was coming straight through the window, so they're not the best. I think I'll probably leave the sleeves this length.
It's a departure for me in style, dressiness, and fabric (currently my only synthetic top). I'm not sure how much I'll wear it, but I think I like it!
