i love all of the bags you‘re deciding between. here are my opinions on each of them:
- the belt bag is gorgeous but i‘ve read and looked up a lot about it and it seems to be the most complicated to use out of the bunch. it‘s kind of a bit of a struggle to open the bag and close it again while actually using it.
- the ysl sac de jour is an absolute classic. it‘s gorgeous, can be dressed down but also looks like an amazing business woman bag! it‘s easy to use but people do say it tends to be a bit heavy
- the givenchy antigona is gorgeous. i tried the small size several times in several different styles and it‘s not for me. i like to put my hands on my shoulders as well as hand-held but it‘s quite bulky on the shoulders. i feel like i‘d constantly run into people with the bag. i ended up going with the mini antigona in smooth black leather and I LOVE IT. if you do consider a mini bag maybe, you could look into the mini antigona. if you mainly use your bags hand held anyway, then the antigona small is a great choice and seems quite a bit more durable than the ysl sac de jour.
