The halter pleated maxi dress is listed with a V-neck, open back and self-tie closure. Those features make the tie tempting to treat as a fit solution. The source does not say where the tie sits or which dimension it adjusts, so start with a dress you already wear comfortably and compare the listed bust, waist and length before relying on the closure.

1. Establish the shape you need

Look at a reference halter or open-back dress in your wardrobe. Note how much back coverage you want and where the neckline sits when you move. The current source identifies an open back and pleating, but gives no back-opening dimensions or lining details. Compare the four actual option photos for the cut, then ask for a back view and the tie location if those details decide whether the dress works for you. A self-tie may change how an opening is secured; the listing does not establish that it can make an undersized bust or waist fit.

2. Compare bust and waist before tying

The S/M/L/XL/2XL chart lists bust 90/94/100/106/112 cm and waist 66/70/76/82/88 cm. The first step is 4 cm at both points; the later steps are 6 cm. For a hypothetical comparison, if a dress you can wear comfortably measures 98 cm at the bust and 74 cm at the waist on the same basis, the M row is numerically 4 cm smaller at both points and the L row 2 cm larger. That arithmetic helps identify which row to ask about. It is not a fit guarantee because the source does not define whether the figures are finished-garment measurements or suggested body measurements, and it gives no stretch value.

Measure your reference dress at matching points while it lies flat. If you double flat widths to compare circumference, use the same method for both dresses. Ask the seller for actual garment widths and whether the tie changes the back opening, neckline position or only closure security. Do not substitute a model’s height or a photograph for those measurements.

3. Check the maxi length separately

Listed length is 144/145/146/147/148 cm from S through 2XL. Even though bust and waist grow by 22 cm overall, length grows only 4 cm. If floor clearance or shoe choice matters, measure the relevant length on your reference dress and ask where this chart starts and ends its measurement. The source does not define that point. Confirm it before assuming a larger size will solve a hem-length problem.

Only after these fit questions are settled should you choose among Green, Red, Blue and Black. The listing does not supply fabric composition, lining or care, so request those details if they affect your underlayer or how you plan to wear the open back.
