Gorgeous, but some big downsides
Color: Pink-upgrade, Size: 14 Inch
I wanted to like this bag SO BADLY. I’ve owned other backpacks by this brand and they have never disappointed. This one though, was a close miss. The color is absolutely GORGEOUS and I almost kept it for that reason alone. However, two big things made me return it: 1) The inside is no longer padded. If you had purchased older Golf Supags backpacks, the interior had padding to help the backpack keep its shape and not slouch over on the floor. That’s gone, so this one does flop over a little. But the big deal breaker: 2) holy cannoli, these straps are WAY too long! On the shortest length, the backpack is still hanging almost halfway down my back. It looks weird, but it’s also not ergonomically good for your back. The actual strap part (with padding) is so far back that the thin seatbelt adjustable material is the only thing on my shoulders. Super awkward. I’m not necessarily a small person either, so I shudder to think what this would look like on someone more petite than me.

Flimsy and cheap
Color: Apricot, Size: 14-Inch
This is the second time I bought a purse online... First was on temu ... Expected to be trash and it was... So I bought this one... And idk what's worse, the temu purse or this one.. only buying them in person from now on unless Its 100% obviously sturdy and of good quality. The fabric and entire purse itself is cheap thin fabric .. not only does it feel cheap it looks cheap. I'm not one to write comments but I'd return it if I wasn't so damn lazy... It feels like the play purses your parents would give you as a kid. Not worth the money. I guess it has pockets, but I feel like my things would be sitting on the floor even though my purse is a barrier and feels like my belongings are not protected in the slightest... Especially not a laptop as advertised.

Beautiful and Well Made
Color: Royal Blue, Size: Small
Remarkable and well made top. It fits perfectly, is super soft and of substantial fabric. The color (royal blue) is vibrant and looks like the picture. It is made and feels like a much more expensive top you would find in an upscale shop. It wears well and you are never hot, just wonderful.

Best white tshirt ever! Will have to buy more
Color: White, Size: Medium
Top is great, better than the expensive designer top I bought. Fabric is so very soft, not super thin and just the right size. I bought a med and it fit perfectly, just right under a jacket or separate. It’s pure white with some stretch if you want a. Lose fit.
