The Delicate Flower sequin maxi lists a concealed side zipper, an organza waist tie and pearl buttons. The tie may change how the waist looks, but the side opening and chest still have to admit the wearer. Make those two checks before relying on a bow to solve sizing.

First confirm the entry

Ask for side and inside views with the zipper open and closed, including where it stops below the waist. The listing does not say whether the pearl buttons open. Measure a lined dress you can put on comfortably and compare its zipped opening and chest with the proposed row; an attractive waist tie cannot enlarge a fixed zip opening.

Then read the waist interval

S gives 31.5 in chest and 23–26 in waist; M 33 and 24.5–27.5; L 34.5 and 26–29; XL 36 and 27.5–30.5. The chest is one value per row while the waist is a range. Ask whether the waist interval is relaxed-to-tied garment measurement, stretch allowance or suggested body size. A hypothetical 34 in chest and 28 in waist could point toward L on the published numbers, but no size is justified until the basis and zip clearance are confirmed.

Place the fixed hem and check coverage

All four sizes list 46 in length. Mark that distance on your reference maxi from the same starting point after asking how this listing measures length. The source says sequin tulle and lined, but not which areas the lining covers or its fiber content. Ask for a current interior photo and a close view of the waist tie attachment if coverage or adjustment matters. This is a planning method, not a wear test of the dress.
