UV Mapping MD to Blender confusion

[AnnaBammaLamma]

Hi, whenever I buy full perm clothes in SL, the UV map looks like I would expect, like the pattern from MD. However when I do a UV Unwrap in Blender, the UV map looks like a mess! I guess I need to do this in blender in order to bake the AO map but I think im doing something wrong! Can anyone help? Also I have Adobe Substance - should I do the AO map in that instead? Im pretty confused!
