Instead of a chambray type of fabric, its really just solid navy blue. QUIT CHANGING THE BOTTOM LAYER ON THE SOLES! My home style is MCM and first saw this stunning wine holder in a vintage photo, researched it and found Amazon had the best price. Would order them again if this one breaks. wouldnt wear these shoes if its wet outside but perfect for a regular day out. Especially at a hotel where they are often lacking! I almost ruined it! Im using these on Bauhn Bluetooth Earbuds (LE34) from Aldi [made for Aldi by an outsource manufacturing company called Tempo] which look very similar to the ones from MPOW and a bunch of other distributors. This should come with an extra sticky double-sided tape piece to keep the lid cover on! I dont personally need the app, but I can see why it would be convenient.
