THIS DRESS IS STRETCHY AND WORTH THE BUY HERE AT FN I USUALLY WEAR A 1XL BUT I GOT THE LARGE AND IT FIT COMFY AND HUG MY CURVES GREAT & SILL I GOT TO KEEP THAT LONG LENGTH SO CUTE CAN BE WORE WITH JUST A PANTY GRIDDLE B/C THE BACK IT OUT. WILL SUGGEST WEAR A LACE BRA SO WHEN IT SHOWS IN THE OPEN BACK IT GIVES A SEXY VIBE SINCE YOUR COVERED UP IN THIS SWEATER DRESS!
