Overall it’s nice but would prefer some small tweaks

This top is nice and breathable. I would prefer if it didn’t plunge down quite so low. I goes very low on me. I like it, but it is costly for what you are getting. I find myself reaching for another brand more often that is also cool, and not quite as costly. I am still considering a different style of top in this brand.

Still waiting for my refund on the wrong size.

This product was ordered as a gift and I ordered the wrong size. I did send it back on January 7th and have not received a credit in my account. I did order the right size and am waiting to give it to my Daughter on her birthday. The night gown is lovely. The color which is mint will be a beautiful addition to my Daughter's wardrobe. She has red hair and green eyes and the color will match perfectly on those romantic nights with her husband. Now I am waiting for my refund and all will be good.
