Key Features

Timeless colorblock design, flattering halter neckline, high brand resale demand for swimwear, tummy-control lining, and modest but stylish cut.

Authenticity Indicators

High confidence. Authentic Boden items feature a multi-tag system including a size tag and a long care tag with a 'Style Code' (e.g., S00XX). Stitching is consistently tight and professional.

Flaws to Note

Check for 'hidden' flaws: hygiene liner presence (if missing, note it), chlorine fading on inside seams, or losing elasticity in the leg openings ('crunchy' sounds when stretched).

Selling Guide

Where to Sell

Poshmark and eBay are the top choices for Boden. Poshmark is excellent for boutique brands, while eBay reaches a wider international audience looking for specific discontinued patterns.

Selling Tips

Always include the US and UK sizes in the title (e.g., US 8 / UK 12). Use keywords like 'Colorblock', 'Halter', 'Retro', and 'Tummy Control'. Photograph the interior hygiene area and the care tag showing the style code.
