Hi All! I want to purchase the reversible ring but not sure on my size and won't have the opportunity to try on multiple sizes b/c my boutique is sold out and I need to try and locate one to order. I have the Cartier nail ring and a perlee band both in 50 but they are a smidge big (i bought them bc the stores didn't have a 49 at the time). I heard from a SA and one lovely TPFer that this ring is running big and to size down. Have you all found this to be the case? Do you think I should go with 48 then or do you think a 49 should work? TIA!
