Hi,
I have had a look and I think this may be a fake. Firstly I don't think that Alexas have been made with a cloche (the part around the plaited handle). The mulberry tree printed on the cloche is not very neat and larger than usual. Also, the poppers on the inside of the bag don't look as good quality as those on a real alexa.
The inside of the bag also looks suspect, mulberrys are very well made and it's rare for the stitching to come away that much- even in a well used bag. There's also the inside pocket where the mulberry round tag is attached. If you have a look at some Alexas online you could compare.
I also don't think that there are usually feet on these bags. Also, any hardware should have a mulberry tree on (the studs on the top of the bag)- it's unclear to see from the pictures posted.
Hope this helps
