Anyone else varying in scrub sizes amongst brands?? I'm 5'7 and 140 lbs approx 34x26x40.. Greys Anatomy tops- S, pants S tall. Cherokee- XS top, S tall bottoms. Carhartt- S top, M tall bottom. HeartSoul- S top, M Tall bottom. Just kind of frustrating going from XS to S to M. Interested in trying Koi and urbane brands, any recommendations for sizes there??
