I ordered this camisole because I needed a bit of support around my mid-section under lower cut summer tops when it's too warm to hide a bit of a bulge under a sweater or jacket.  I truly love this item and wear it on a very regular basis.  I like the freedom of being able to wear my bras with it and the support it provides.  It's not a miracle slimmer but I didn't need to hide a lot.  I can understand where it might be a bit uncomfortable under the arms for some since I slightly notice that fact but am so thrilled with the look it provides, I'm willing to overlook that very minor discomfort.  I must order another one since this one will surely wear out for as often as I wear it.
