I own 10 Robinson Double Zips, 4 Amanda totes, 4 Jaden totes, 3 Ellas and a ridiculous number of wallets. I returned Slouchy Marion and the Thea tote in Blush because they really weren't my style.
I use all my TB bags and do not baby them. I also travel with them. The Robinson Double Zips have held up the best, some better than others. My Cobalt Blue and Black w/ Patent corners wear like iron. Blood Orange disintegrated quickly, numerous spots with cracking and peeling leather and the leather wore off the handles after like five uses. Sand gets dirty too easily and Parisian Blue is prone to creasing. Zero issues with any Amanda totes and wallets. Jadens are okay but the corners are prone to holes much like Le Pliage totes. The Ellas are complete garbage. Trim is coming off the handles and the bags are completely fraying. One tip that I will pass on is that I have treated all of my bags with LovinMyBags handle cream because the leather completely wore off my Blood Orange Robinson after only a few wears and this freaked me out.
LMB's cream has really helped to slow down the wear of all my bag handles from TB to my LV Empreinte.
I own an equally ridiculous number of Revas. Tumbled leather and patent hold up the best. Vegetable tan is the most delicate and starts to show wear really easily. The leather Revas from the last two seasons are complete garbage to me because medallions have fallen off and there is even a hole in the sole of one. I wore the shoe no more than 3x. This is completely unacceptable for a $200 shoe.
I own several TB blazers and jackets and have no issues with them. I own a dozen Simone cardigans and they are all holding up really well.
I think TB's quality, like almost every other designer out there, has decreased significantly in recent years but at sale prices most products are worth the money. My Robinsons are faring better than my
Prada totes and those were almost 4x the price. My Miller sandals are faring better than my Hermes sandals which are almost 3x the price.
