The Gallery Dept Pocket English Print Sleeveless T-Shirt in Black lists a loose fit and sizes S through XL. Its own chart gives a more useful distinction: the chest entry increases by 6 cm between sizes, while shoulder and length each increase by 2 cm. Choosing a larger size therefore changes the proportions, not just the letter on the label.
This article reads the chart and catalog photos for SKU GALLERYDEPTtshirt20250705002. It concerns a UA-reps listing; the name, printed logo, and label do not establish retail authenticity.

The chest column needs a measurement definition
The figures below are transcribed from the black tee’s size-chart image. They are the seller’s reference values, rather than measurements of an individual garment.
| Listed size | Shoulder | Chest | Length |
|---|---|---|---|
| S | 54 cm | 112 cm | 68 cm |
| M | 56 cm | 118 cm | 70 cm |
| L | 58 cm | 124 cm | 72 cm |
| XL | 60 cm | 130 cm | 74 cm |
The image labels its column “Chest” without explaining the endpoints or whether this means garment circumference. Confirm the method before comparing it with a tape measurement. If the values represent twice the flat chest width, they imply widths of 56, 59, 62, and 65 cm respectively. Those halves are a conditional calculation, not an additional size specification.
For example, a favorite sleeveless top measuring 59 cm across would match the M row under that interpretation. It would still be necessary to compare length, shoulder coverage, and armhole opening. Matching one number does not establish a fit.
Going up one size adds width faster than length
Across S to XL, the chart adds 18 cm to chest but only 6 cm to length. Between adjacent sizes, the conditional flat chest width rises by 3 cm, alongside 2 cm more length. If your concern is primarily hem position, moving up a size also accepts a wider body and broader shoulder measurement.
Lay out a sleeveless top whose proportions you already like. Record its chest width, shoulder span, and length using clearly identified endpoints, then ask for the same measurements on the black tee in the size under consideration. The chart notes a possible 1–3 cm manual-measurement error, so a small numerical difference should prompt a method check rather than a precise fit prediction.

The missing dimension is the armhole
The front photo shows shoulders extending toward the open armholes and a small printed pocket on the wearer’s left chest. The chart supplies no armhole depth or opening measurement. That omission matters when choosing between wearing this tee by itself and layering it over another top: chest room does not tell you how much side coverage the opening provides.
Ask for a flat photograph of the chosen size with the armhole endpoints identified, plus a measurement made by the same method on your reference top. Also compare where the pocket sits relative to the neckline and opening. The catalog photo can guide that request, but it cannot establish the drape or pocket position on a particular wearer.
Make the size request specific to the black pocket tee
A useful request names GALLERYDEPTtshirt20250705002, the selected letter size, and the three unresolved details: what the chest figure measures, how length is taken, and the armhole dimensions. Include your reference garment’s measurements with the methods used. This gives the seller concrete questions to answer without relying on a broad “loose fit” description.
Return to the black pocket sleeveless tee listing to check the available selection. Choose only after the width, length, and opening evidence fits your intended use; the chart does not support a universal instruction to size up or down.
