I love the detail on this J.Crew peplum top (available on Amazon with Prime shipping). The embroider detail is PERFECTION. It's a subtle way to do Fourth of July colors. I'd pair it with a pair of white shorts or white jeans. SO cute.
If you'd prefer to wear shorts, try these paper bag ones from J.Crew that are on sale right now. Super cute style made with comfortable cotton. You can dress them up or down. If you'd prefer a solid color vs. print then try these (from the Gibson x HiSugarplum line).
This is the perfect red, white and blue dress. Super cute wrap style (runs a bit big in chest area) dress with pulls of the patriot colors throughout. You can definitely dress it up or down. Great Target price point.
Here's another red, white and blue print dress. Very flattering silhouette. Straps are thick enough that you can wear a bra with it. Very comfortable too. And another great Target price point.
If you'd rather a more subtle print in a dress then try this navy and white polka dot one from Amazon. Super comfortable. Another one you can dress up or down.
If you don't want a print at all then here are some fabulous solids with both dresses and rompers (my favorite). Varying price points from Amazon and Nordstrom. You can't go wrong with any of them. Fit is true to size across the board (I'm in petites for the rompers).
