The short answer: pick by fabric and colour, not by coverage
Both the Curvy Kate Everyday Full Brief and the Smoothie Full Brief are designed for everyday wear and are cut as full briefs, so the coverage comparison is close. The clearest differences are the fabric blend and the colour: the Everyday Full Brief in Deep Red is 87% polyester and 13% elastane, while the Smoothie Full Brief in Latte is 77% polyamide and 23% elastane. Both have a 100% cotton gusset lining. If you want a deeper, more saturated colour, the Deep Red stands out; if you prefer a softer neutral, the Latte is the obvious choice. The higher elastane content in the Smoothie may feel more stretchy, but the supplied information does not include a stretch test, so treat that as a reasonable expectation rather than a confirmed performance claim.
Fabric and feel: polyester vs polyamide
The composition is the most concrete difference between the two briefs. Use it to decide which one matches the feel you want against your skin.
- Curvy Kate Everyday Full Brief Deep Red: Main: 87% Polyester, 13% Elastane. Gusset Lining: 100% Cotton. The higher polyester share suggests a smooth, durable everyday fabric, though the supplied record does not describe a specific hand-feel.
- Curvy Kate Smoothie Full Brief Latte: Main: 77% Polyamide, 23% Elastane. Gusset Lining: 100% Cotton. The higher elastane share may give a more forgiving stretch, but this is not confirmed by a fit test in the supplied information.
Coverage: both are full briefs, so the difference is small
Both styles are described as full briefs and are designed with every curve in mind. Neither record includes measured rise, leg-opening or back-coverage dimensions, so there is no evidence to say one gives meaningfully more coverage than the other. If coverage is your deciding factor, the honest answer is that the supplied information does not separate them on that point. Choose based on fabric, colour and size availability instead, and treat any claim of extra coverage as unverified.
Sizing and availability
Both briefs are offered in the same two size options, so sizing does not separate them. The decision comes down to which size range fits you and whether your preferred colour is available.
- Everyday Full Brief Deep Red sizes: Available in S/M and L/XL.
- Smoothie Full Brief Latte sizes: Available in S/M and L/XL.

How to choose between them
Use these decision rules to settle on one brief without overthinking it.
- Choose the Everyday Full Brief Deep Red if:: You want the lower catalog price, a deeper red colour, or a polyester-based fabric. It is the straightforward pick when budget and colour are your priorities.
- Choose the Smoothie Full Brief Latte if:: You prefer a neutral latte shade or want the higher elastane content (23% vs 13%). The polyamide blend is the main reason to pay slightly more.
- If coverage is your only concern:: The supplied records do not give measured coverage for either brief, so there is no evidence-based winner. Try the size that matches your usual Curvy Kate fit and judge from there.
What the supplied information does not tell you
Neither record includes care instructions, washing guidance, measured rise or leg-opening dimensions, or a fit test. That means you should not expect this comparison to tell you which brief washes better, which sits higher on the waist, or which feels softer after a full day. The records also do not confirm any smoothing or shaping effect, so treat the Smoothie name as a product name rather than a performance promise. If those details matter to you, check the full product pages or contact the store before ordering.
