Even though I enjoyed using the Echo Look, I can't see myself using it regularly.
Having photos of your favorite outfits is useful in case you forget about a combination you like, or you can't remember when you last wore something, but I could do that myself with a selfie stick.
The style-check feature is fun, but the reasons it chooses one outfit over another are sort of vague. When it says the outfit shape works better for me, I want to know more about the reason why — then I could use that information to make better fashion decisions in the future.
That said, if you're in the market for a virtual assistant, like Alexa, the Echo Look styling feature is an added bonus. You can order it for $199 over on Amazon.
