Grey (described as grey marl on label) ribbed sleeveless top from the Goodmove activewear range at Marks & Spencer.  Size in it is UK/AUS/NZ 10, EUR 38, CAN/US 6 - approx underarm measurement is 16.5in/42cm and length from shoulder 23in/58.5cm (please check measurements - it has stretch to it).

New with tags so in excellent condition, just creased from storage.

Please look at my other items.  I combine postage and keep postage costs down to a minimum by sending 2nd class large letter/Evri (depending on size) within the UK.  If you would like a different form of delivery let me know and I can calculate costs.  I post abroad but only using Ebay Global Shipping Programme.
