I am a 17 1/2 Neck and an exact 34/35 sleeve in all Men's dress shirts EXCEPT for this one.  I wanted to give this a try because of the great price.  I read the other reviews regarding the sizes and ordered an 18 neck, 34/35.  The neck was perfect, but the sleeves only came up to the top my wrist.  Reality was that even tho the shirt says 34/35 it's truly a 32/33 sleeve.  I sent it back and am awaiting my replacement of 18 Neck 36/37 sleeve.  The quality felt good, and I like the versatility of the cuff link and button duo.  However, the sizes should be more precise.  So lesson learned, Order one size bigger both neck and sleeve length and you will be happy.
