Rectangle mini! I think the coco handle looks better in the bigger size... Also, just not a huge fan of the coco handle in general, imo.
What colour and finish are they?
Both are super cute.
If you want something a bit different the Coco is great [emoji177]
How do you like wearing your bags?
Rectangular can be worn crossbody where as Coco is more of a shoulder bag.
So when you say caviar and same color, I'm guessing it's black since there are not many recent caviar mini available same as the coco's. Anyways, for the Coco, only sizes bigger than Small can really be cross bodied. I find the mini coco very cute but due similar size as the square / rectangular mini BUT with the narrower top due to the shape of the bag, it fits less stuff. I can easily fit my essentials into the rectangular mini, but cannot make them work in the mini Coco (so I bought the small size instead). I only carry my key case, phone, chanel snap button card holder, and a lipstick. Hope this helps. They are both beautiful bags and you should be pleased either way, it's more about which one fits your need better.they are both caviar, same color...and i like wearing crossbody too..somehow i thought the coco handle strap can be worn crossbody?!
