This is such a fun holiday dress! Perfect for date night or parties. Go with your regular dress size. Im in a medium- would prefer the large overall. Tiers arent stretchy but fall really nicely! There is one toggle looped button under the first rhinestone bow. Use fashion tape to secure deep V if needed. Im wearing just cakes covers here. LTKfindsunder100 LTKmidsize LTKHoliday
