lululemon new arrivals try on haul Top size XS (typically I get a 4 in these and would say the XS fits great. It is more of a classic fit now. I found the previous Swiftlies tight under the arm and a slim fit. This one gives a bit more room in both areas but it's not oversized or boxy.) Leggings size 4 (true to size). I get a size 4 in my aligns and wunder trains and the 4 in the wunder unders fit perfectly! A little bit of compression but not as much as their fast and free leggings. These are great if you have pets or hate lint sticking to your leggings! They have a sleek feeling inside and out. LTKcanada LTKfall LTKfitness
