Sock Dreams may be an e-shop specializing in a veritable buffet of socks in more colours and styles than you can imagine. They also tend to cold arms and hands, too!
These arm warmers are very inexpensive for the quality. They look and feel costly and luxurious. The purple and black textured colour is beautiful and stands out in a subdued way. They are indeed warmers--in the cold of late-December in the Midwest, I braved the outdoors for hours and my hands were toasty.
I cannot think of much negative to say! They can be a bit itchy for very sensitive skin, for sure. Also they do not protect the fingers for the cold. Other than that they are a very affordable product that comes in a variety of colours. They fit snugly on my very small arms and wrists. The fit is extremely-flattering and attractive. They will certainly stretch to fit larger arms. If you have a dislike of synthetics, these are mostly acrylic, so bear that in mind.
Certainly, I plan to order more pairs in more colours. They're cute enough to be sassy but classy enough to be taken serious in. They're durable, affordable, and warm--the perfect arm warmer!
