Giving up sports bra for leos.. need help!?

Ok well im tired of feeling so boyish sooo.. i bought some leos (and yes, skirts!) sooo. its like super hot in our studio and after 10 min your dripping w/ sweat so do the leo's feel much different? She sold me the nylon/lycra kind bc she said they have a better feel to them. Are they supposed to feel like they suck u in? should i really wear this to practice in or does it feel weird? it kinda feels like it sticks to ya! :-P What do your s feel like??
