Whenever I wear sunscreen on my arms and shoulders, the straps of my bags seem to get sticky from being in contact with the sunscreen. I've tossed away two bags (luckily they weren't expensive ones) because I couldn't stand how sticky the straps felt. So I'm really afraid to and haven't yet used my LV's when I'm wearing sunscreen. Does anyone else have input about this topic? I'd love to use my BH and mono Speedy in the summer but I'd like to know if they might get ruined from the sunscreen. TIA!
