The absolute most important is fit and cup construction! I find that when you wear a perfectly tight fitted band around your back and the cup can gather all the breast tissue properly you'll get a great look (and omit stupid padding). That said, Bradelis actually has a "system" which I never paid all that much attention to but apparently it's a lifting type system using their different bras in steps, if you follow the steps you may see permanent improvement . I own many of their bras but my favorite is their 7521 push-up bra (aka the step 1), great for everyday and then some as far as I'm concerned..... I own about 8 of them..... My other favorite is from their "premium" line, the CA18112 Rosemary Push-up which is a balconet style push up. For me the first is a little more versatile because it plunges lower but I love them both! Actually I love every bra I own from them honestly and I'm very critical! I was always stuck buying 32 C's which were too big around my back so when I found the 30 D's AND the great cup construction on these bras I knew these were it for me.Lola thank you! Yes, I would like to know the specific style. I have tried push ups but, I really don't see a big improvement as far as the big boobie look in a cute dress or top.
