Lululemon hold tight tank

Lululemon hold tight tank Colour is burnt orange/brownish Pit to pit is 14” comfortably stretches to 19” I’m normally a size 8 and it fits me but neck hole is a little too tight for me so I would say it’s either a size 4 or a 6, maybe more of a 6. Worn once only as mentioned above the neck hole is a little too tight for me
