I'm not sure what your budget is but David's Bridal has reasonable prices. Also you can try preownedweddingdresses.com or recycledbride.com or oncewed.com. As the warning in the sticky at the top of this forum states, stay away from knock-offs.  I agree with this because a friend of mine purchased a dress online from a Chinese site and the $300 she spent to get a Caroline Herrera inspired gown went down the tubes and good luck getting your $ back.... they are in China and international lawsuits are not worth it over a $300 gown. Also, you can check out sample sales or have you looked into renting a gown? I don't know about Milwaukee but here in LA we have places where you can rent a gown.  I would honestly just try to stick to buying something you have tried on before unless the return policy is solid. No matter your budget, you still want it to be flattering and really be you... this is possible no matter what price range you are looking at, but I would start with sample sales. Check out this place in Wauwatosa, it says they have gowns as low as $350 http://www.kaybridalshop.com/#!our-pricing and ooh ooh just googled and found this place that is having a sample sale right now in Milwaukee http://www.missrubyboutique.com/happenings.html.  Good luck!
