💥Tennis Dress 🎾 with peek a boo back!

How cute is this one piece? It's casual, flirty and cheery. Comes with gold belt! It says "XL" but I am listing it as medium because it's more a M/L fit. Fits me great as a size 8. Armpit to armpit is 18.5". Neck to waist is 11". Elastic waist unstretched is 13" and 17" stretched. Skirt is 17". JUST LOWERED the price because of little 1cm gummy mark (can prob be scrubbed out) on front.
