Mkt is an amazing platform for easily browsing through the latest collections of many designers across multiple retailers in one go! Instead of having to go to NeimanMarcus, then Saks, then MatchesFashion, I just go to Mkt now. Time saver.
P. s: I found the loveliest heels on it today, and it even found it at a discount for me!
Net-a-porter has always been my go-to for shoes and bags, I love it! However I once had to return an order and did not have the best experience with their customer service... so I will say this: great if you love what you bought, not-so-great if you don't.
