not for big boobs at all but the sizing is accurate u will have slips and its very awkward in the arms it doesn't look good up or down .... its just awkward arm placement but it is really cute

Cute crop top got it a size L usually wear a M but since is a crop top wanted a lil more comfort the arms were not long enough unless I pull sleeves down making the top into one of those shoulders crop top. Point is get it your actual size and if you dont mind the sleeves you should be ok
