Cute great size got a lot of compliments
Color: Obsidian Black
Loved this. Got it on sale dor 34.99 and worth it it seems like a good staple for events / outtings. Even daily use probably, but I got it for a wedding event.weekend and got so many compliments!
Good closure zipper had no issues.
I like the material doesn’t look or feel cheap, good color. (I got black) but saw someone at event with gold one and also adorable!!!
Storage is huge for me - it easily fit my phone, a couple of pads and tampons, small hand sanitizer, small aquaphor with room! I also had sunglasses in there at one point and surprisingly zipped fine with all of that.
Overall convenient for storage, aesthetically pleasing, good material-quality.
Cons: the chain strap bothered my neck a little bit after wearing it but that’s a me problem. Not the purse/way it was made. But something to consider.
