Sizing & Fit Guide for Emama Black Long Line Nursing Crop (UK/AUS conversions included)

Introduction The Emama Black Long Line Nursing Crop is designed to support you through nursing with a long-line silhouette and flexible cup construction. Because sizing can vary by band length, cup depth, and nursing features, this guide walks through the sizing process using your measurements and how that translates across UK and AUS sizing. It also covers how the fit feels in real life, common fit issues, and what to consider if you’re between sizes.

Sizing Answer (quick recommendation) Based on your measurements (bust 92 cm, underbust 82 cm) and current nursing status, a nursing long line bra around UK size 34D/34E (roughly AUS 12D/12F depending on the chart) is a common starting point for a snug-to-flexible daytime fit. Because you’re nursing, you’ll want a cup depth that accommodates fluctuating breast size without pinching. If you prefer a snug fit that provides strong daytime support, aim toward the lower end of the cup range; if you want more breathing room or variable cup depth during pumping, a slightly larger cup may feel more comfortable. Always confirm against the official Emama size chart for your region before purchasing.

Customer Questions (from the chat)

What size would you recommend? – For bust 92 cm and underbust 82 cm while nursing, a nursing long line bra in the 34D/34E range (UK) is a practical starting point, with AUS equivalents around 12D/12E depending on the brand’s cup depth. Since you’re nursing, prioritize a flexible cup that can accommodate size changes across feeds while maintaining comfortable support. Can you compare in AUS size? My pre-pregnancy cup was 12D. – In AUS sizing, a pre-pregnancy 12D often translates to around 12F or 12G in many brands, but cup depth can vary. For nursing wear, aim for a flexible cup with snug support to adapt to fluctuating sizes. If you were comfortable at 12D pre-pregnancy, trying an AUS 12F/G in a nursing-long-line style is a reasonable next step, paying attention to the band snugness and cup depth to avoid overflow or gap at the top.

How It Fits (real terms)

• Cup depth and coverage: The Long Line Nursing Crop typically provides extended band length with a longer front underbust, which can give extra support without compressing the torso. Expect a cup that accommodates nursing-related fullness with some stretch across the fabric.
• Band and underbust: The underbust measurement (82 cm in your case) helps determine your band size. In many UK charts, this would be close to a 34 band, but confirm with the official chart as there can be slight shifts between brands. A snug band helps lift and support without digging in when you’re actively nursing.
• Cup shape: Nursing bras often use a cup that has additional elasticity or a slightly shallower depth to accommodate changes in breast size. If you found a size small previously that was too tight, it likely lacked sufficient cup depth or stretch, not just the band.
• Long line benefit: The extended bottom band offers more anchoring surface, which can improve comfort for larger busts or sensitive ribcage areas, particularly when you wear the bra for longer periods or during activity.

Size Recommendations (practical guide)

• Step 1: Confirm your measurements in your region’s sizing chart (UK/US/AUS charts can differ). For UK sizing, bust 92 cm and underbust 82 cm commonly map near a 34 band with a cup depth around D to E. For AUS, translate to roughly 12D to 12F/G depending on cup depth as noted.
• Step 2: Choose cup depth based on nursing needs:
  • If you experience significant breast changes across feeds and want secure coverage: lean toward a slightly deeper cup (near the upper end of the suggested range) while ensuring the cup doesn’t feel compressed.
  • If you want a more flexible cup with easier nursing access and less cup pressure: choose a shallower cup depth within the same size range and rely on the band for support.
• Step 3: Consider the band fit:
  • A snug band is essential for support, especially during nursing moments when you need lift and hands-free access.
  • If the band feels too tight, you may be between sizes; consider the next band up with a correspondingly adjusted cup depth, or try a brand’s sizing up option if they offer it without changing cup depth too much.
• Step 4: Between sizes:
  • If between sizes, prioritize cup depth and comfort over minor band tightness. A slightly looser band with a deeper cup can reduce spillage and provide more nursing-friendly coverage.
  • If you expect ongoing weight changes or heavier nursing days, you might prefer a size up with a flexible cup rather than a size down that pinches or causes overflow.
• Step 5: Try multiple options within the same size range if possible, focusing on brands that offer nursing-friendly stretch fabrics and adjustable straps.

Common Fit Issues (what to watch for before purchase)

• Overflow at the top or sides: Often indicates the cup is too small or the cup depth is insufficient for your current nursing size.
• Band riding up at the back: Could mean the band is too loose or you’ve chosen a cup that shifts breast tissue away from the center.
• Gapping between cup and breast tissue: May signal a cup depth that’s too shallow for your nursing size or a poor match for your breast shape.
• Uncomfortable underbust pressure: If the band feels tight across the ribcage, consider trying the next band size up with a corresponding cup depth.
• Straps digging or slipping: Could indicate a band too tight, or straps not properly adjusted for your height and torso length. Look for adjustable straps with adequate length range.

Between Sizes: Should you size up or down?

• If you’re between sizes and nursing changes are common, sizing up can reduce spillover and provide more room as milk supply fluctuates. A slightly looser band with a more flexible cup can feel more comfortable for daily wear and during pumping or feeding.
• If you’re on the edge of a snug fit and value lift and silhouette for all-day wear, you might prefer staying in your current band with a cup that’s a touch deeper. In this case, check if the brand offers different cup depths within the same size or has a more supportive fabric option.

Practical Fit Scenarios by Body Type

• Petite frame with average bust: A 34D/34E in UK sizing can be a good starting point; ensure the band sits evenly around the torso and the cups don’t press into the tissue near the armpit.
• Full-busted or wider ribcage: A longer line band tends to help distribute weight more evenly. Look for extended underbust support and a slightly deeper cup if you need more room at the apex.
• Nursing-heavy routine (frequent feeds, pumping): Prioritize a flexible cup and a snug band that remains comfortable after milk production changes. A longer line with reinforced stretch materials can reduce the need for constant adjustments.
• Asymmetric nursing sizes (one side larger): The adjustable straps and stretch in the cups help accommodate size difference between breasts. Look for cups with some built-in stretch or a design that allows a gentle spillover on the smaller side without compromising coverage on the larger side.

How to measure accurately at home (quick steps)

• Underbust measurement: Use a soft measuring tape just under your bust. Round to the nearest centimeter. This is your band size in many UK/AUS charts (e.g., 82 cm underbust maps to a 34 band in common UK sizing).
• Bust measurement: Measure around the fullest part of your bust with a gentle, level tape. This helps determine cup size in combination with the band size.
• Cross-check with the brand’s size chart: Sizing can vary by brand and by line within the same brand. Emama’s nursing line may have slight differences from everyday bras, so always compare your measurements to the specific size chart for the Nursing Crop.

Tips for trying on (when you can try in-store or order multiple sizes):

• Assess the cup position: The nipples should sit centered in the cup with no quad-boob escaping at the top or sides.
• Check the band tension: You should be able to fit two fingers under the back band with some resistance; the band should feel snug, not painful.
• Evaluate the cup depth while nursing: With nursing, breasts can swell during feeds. Test with one or two feed cycles to ensure the cup depth accommodates changes without spilling or pinching.
• Test the clasp and straps: If adjustable, ensure straps hold the cups in place and don’t slip off the shoulders as you move or lean.

Conclusion and next steps

• Start with UK size 34D/34E or AUS 12D/12F as a baseline, then adjust based on how the band feels and how the cups accommodate fullness during nursing.
• If you’re between sizes, prioritize a flexible cup and snug band together; consider sizing up if you experience consistent overflow or band compression.
• Always reference the official Emama size chart for your region to confirm the exact mapping from bust/underbust measurements to band size and cup depth.
