Hi John,
I've used the following in the past for my tees and also purchased the FOTL jog pants for a dance troupe customer.
www.uklonline.co.uk
Also try
www.polo-shirts.co.uk as they have a very large range of tees in various colours and sizes.
Use
www.themagictouch.co.uk for white tees as these are great for printing too and the Hanes tees are the best price around if bought in quantity.
Not sure about the slash neck tees but one of my customers owns a DanceWear shop which she has had for many years and said that unfortunately the slash neck look you are looking for is customised, i.e., tees bought and then "slashed" to the wearers needs!
Hope this helps.
Sue
