I think you meant 2 shirts for 5.50 dollars. If so, 5 shirts will cost 5.5 X 5/2 = 27.50/2 = 13.75 dollars Note that if the offer is buy 1 and get 1 free, the above will not work out. You will end up with either 4 shirts for 11.00 or 6 shirts for 16....
Try Abercrombie and Fitch. They have fitted shirts. Also try threadless.com. Those shirts are slim fit. I'm pretty sure Volcom and quicksilver sell fitted shirts also. Try dry fit shirts as well. I hope I answered you question : / Good Luck!
No. The women's shirts are too flowery and look like they were designed using clip art. The men's shirts are not anything different. They look like cheap knock-offs of Affliction shirts.
