i didnt realise i can use it as clutch too! Thanks for sharing your opinion with me, i think i will try on both bags to see which one is easier to match my style too.
I vote for the YSL! Both are very pretty but the YSL is a lot more uncommon than the celine, and more understated too, because not many know people know about this design. Also, depending on your frame, I feel that the celine box tends to looks a bit too large on more petite girls.
