Eliza J Women’s Floral Square Neck Midi Sundress
This floral square neck midi sundress is our answer to the woman who wants one dress that transitions from weekend brunch to garden weddings without missing a beat. We crafted it from a lightweight cotton-blend poplin that holds its shape through humid afternoons while letting your skin breathe.
The square neckline sits just below the collarbone — high enough for daytime ease, low enough to frame delicate jewelry. Our signature gathered empire waist skims the figure without clinging, then flows into a midi-length skirt that hits mid-calf on most frames. The all-over vintage-inspired floral print pairs soft blush tones with sage green leaves on an ivory ground, making it a neutral canvas for nearly any accessory palette.

What the numbers mean
We source our cotton-blend poplin from mills in Portugal known for soft-finish weaves that resist wrinkles better than pure cotton. The 60/40 cotton-modal blend gives you the breathability of natural fiber with the drape and color retention of a performance modal.
Every seam is double-stitched and finished with French seams at the bodice for a clean interior. The empire waist uses elastic casing stitched into the seam allowance — it shapes without binding or rolling. We left the skirt unlined intentionally; a second layer would trap heat, and the poplin weight is opaque enough to stand on its own.
This dress runs true to Eliza J sizing. The adjustable tie straps let you raise or lower the neckline up to two inches, which shifts the empire waist placement slightly — taller frames often prefer the straps tied shorter to keep the waist seam at its natural spot.
If you’re between sizes, we recommend sizing up if you prefer a looser fit through the bodice or if you plan to wear a strapless bra with wider bands. The gathered waist is forgiving, but the square neckline and armholes are cut close to the body for a tailored look. For petite frames under 5’3″, expect the hem to fall closer to the ankle; for taller frames over 5’9″, it may land just below the knee.
We designed this floral midi sundress to anchor a warm-weather wardrobe without requiring a full outfit rethink every time you wear it. Pair it with flat espadrilles and a straw tote for farmers market mornings, or swap in block-heel sandals and a structured clutch for outdoor wedding receptions.
The ivory-based print plays well with gold, rose gold, and brass jewelry. For cooler evenings, layer a cropped denim jacket or linen blazer over the shoulders — the square neckline shows just enough to keep the silhouette balanced. If you gravitate toward prints but want a lineup that feels cohesive rather than chaotic, the soft blush-and-sage palette in this piece mirrors the tones found in many of our cocktail dresses, making it easy to build a capsule around similar color families.
Care instructions
Machine wash cold on a gentle cycle with like colors. We recommend turning the dress inside out to protect the print from abrasion against other garments. Skip the dryer — hang or lay flat to air dry.
If wrinkles appear after washing, a warm iron (not hot) on the reverse side will smooth the poplin without flattening the gathered waist. For travel, fold the dress lengthwise and roll from hem to neckline; the poplin resists deep creasing, and any lines will relax after an hour on a hanger. Avoid bleach and fabric softener, which can dull the print and break down the modal fibers over time.

What the crews say
Common questions about this floral midi sundress
Yes, this dress runs true to Eliza J sizing. The adjustable tie straps give you flexibility to customize the fit through the bodice and neckline. If you’re between sizes and prefer a looser fit or plan to wear a wider-band strapless bra, we suggest sizing up. The empire waist has gentle gathering that accommodates a range of proportions.
The dress measures approximately 48 inches from shoulder to hem on a size 6, which translates to mid-calf on most frames between 5’4″ and 5’8″. Petite frames under 5’3″ may find the hem closer to the ankle, while taller frames over 5’9″ will see it land just below the knee. The adjustable straps let you fine-tune the overall length by raising or lowering the neckline.
Yes, machine wash cold on a gentle cycle with like colors. Turn the dress inside out to protect the print and hang or lay flat to air dry. Avoid the dryer, which can shrink the cotton fibers and fade the floral print. If needed, use a warm iron on the reverse side to smooth wrinkles. Skip bleach and fabric softener to preserve the modal blend and color vibrancy.
The bodice is fully lined for opacity and structure, but the skirt is unlined to maximize breathability in warm weather. The poplin fabric is substantial enough to be opaque on its own, and leaving the skirt unlined prevents the dress from feeling too heavy or trapping heat during humid days.
This dress works for a wide range of warm-weather events — garden weddings, bridal showers, outdoor cocktail parties, vacation dinners, or daytime gatherings. The floral print and midi length strike a balance between casual and dressy, so you can dress it up with heels and statement jewelry or keep it relaxed with flat sandals and a straw bag.
The shoulder straps feature fabric ties that you can knot at your preferred length. This lets you raise or lower the square neckline by up to two inches, which also shifts the empire waist placement slightly. Taller frames often prefer shorter ties to keep the waist seam at its natural spot, while petite frames may tie them longer for a lower neckline.
Yes, this floral square neck midi sundress is offered in sizes 0 through 16 in our regular range and 14W through 24W in plus sizing. Both size ranges feature the same adjustable straps, gathered empire waist, and midi-length skirt to ensure a flattering fit across all body types.
