I cannot decide if this one or the Muted Goldfish Knit Button Up are my favorite shirts that I own... luckily I can rotate between them! Great quality, fits perfect, even after washing multiple times.
Your hair is AWESOME! Thanks for the kind words.
This is a sharp looking shirt! Every time I wear it, I get loads of compliments! It's well-made, just like all of the clothing made by this company. I'm totally hooked on Sleepy Peach 🍑💚
For legal purposes I must state that this shirt does not *actually* slap. Thanks for the kind words!
Well made shirt on all levels. Feels great, many compliments on the colors and style. Just a comfortable fun shirt.
Love it. More please Sleepy Peach!
Love the fit and comfort on this top. Ordered a slightly larger size than my actual measurements means it fits pretty well over my chest. Heads up though- the spacing between the buttons is wide and between the 3rd and 4th buttons there can be some gapping over the chest. Be sure to check the measurement chart and go for the larger size if possible.
