I think Trendi application is definitely not finished because it doesn't display the items you are buying so you never quite know what you are going to get. Also, I was under the impression that the new clothes will be unlocked pretty much like the Nifty Knitting ones, but they don't seem to unlock, and you can't edit the outfits you buy, so you are stuck with the surprise outfit you bought. My sim bought that Nr. 2 outfit and I wanted to remove the socks and it wasn't possible, so I ended up sending the outfit back where it came from. Also, these outfits don't seem to appear under the Change outfit interaction, they are only available from inventory, but, again, there's no preview available to see what the outfit looks like unless your sim wears it. If you want to keep several such outfits so your sim has more clothing choices, it's not easy to tell which is which because there's no preview for the outfit.
