i'm on the verge of buying an ivory YSL O/s muse. just need to save up a little more for it! i tried on both the large and the o/s and decided the o/s looks better on me,even tho' it's HUGE! i've asked the SAs in YSL several times on various occasions re. putting my macbook in the muse. they assured me that there should be no problem. has anyone here had any problems with putting a laptop in ur o/s muse? thanks!
