Quick Answer
To get the best fit from the Square Black Archive, focus on adjusting the straps and positioning the underwire so it sits flat against your ribcage. If the underwire digs or the neckline gaps, you may need a different size or style.
Why the Square Neckline Needs Special Attention
The square neckline is a flattering, retro-inspired shape, but it can be tricky to fit. Because the neckline is wide and straight, it relies on the built-in underwire and straps to stay in place. If the fit is off, you might see gaping at the edges or feel the top shift when you move.
The Square Black Archive is designed with a hidden in-built underwire bra and powermesh sling, which means the support comes from the structure, not just the fabric. This is great for D+ sizes, but it also means the underwire needs to sit correctly to avoid discomfort.
Trade-Off: Support vs. Flexibility
The built-in underwire gives you lift and shape, but it also makes the top less flexible than a wirefree style. If you prefer a more relaxed fit or have a short torso, the underwire might feel restrictive. In that case, consider a wirefree option like the Wirefree Basil Top, which offers support without underwire.
The Square Black Archive also has adjustable straps, which help customize the fit, but you'll need to spend a little time getting them right. The payoff is a secure, lifted silhouette that stays put.
Diagnosing Your Square Black Archive Fit
- Symptom: Gaping at the neckline edges: If the fabric pulls away from your chest at the sides, the top is likely too big or the straps are too loose. Try tightening the straps first. If that doesn't help, consider a smaller size. Tighten straps before sizing down.
- Symptom: Underwire digs into your ribcage: The underwire should sit flat against your sternum and ribcage, not press into them. If it digs, the band may be too tight or the cups too small. Try a larger band or a different style with a softer underwire. If digging persists, switch to a wirefree style.
- Symptom: The top shifts or rides up: This usually means the band is too loose or the straps are too long. Adjust the straps to lift the bust, and make sure the band sits snugly under the bust. If it still moves, the size may be wrong. Check band fit; consider a smaller band size.
Product Facts
- The Square Black Archive: The Square Black Archive features a hidden in-built underwire bra and powermesh sling engineered for D+ sizes. This means the top offers real support, but you need to ensure the underwire sits flat and the straps are adjusted properly to avoid digging.

If you've tried adjusting the straps and the underwire still doesn't sit comfortably, the Square Black Archive may not be the right shape for your torso. In that case, explore other Form and Fold tops with a different neckline or support system.
