i've been plagued about the LV damier azur speedy 25 or 30 question -- apparently like some others on here! so i know in the pic of hilary duff where she's wearing black, it's definitely a 30. but in the pic of her in white sweatpants, it looks like a 25 to me. is it? or is it still a 30?? someone please help! i'm not sure which size to get. i feel sometimes the 30 overwhelms me... and sometimes it's fine. and sometimes the 25 feels small, but sometimes i think it's fine. i'm confused. please help!
