How do I find my correct bra size?

Start with a soft tape measure and measure directly under your bust for your band size. Then, measure around the fullest part of your bust without squashing or lifting. Now, the magic happens: subtract your band size from your bust measurement. The difference reveals your cup size. Example: Underbust: 86cm Bust: 96cm Difference: 10cm = B cup But numbers alone aren’t the whole story. If you’re not sure about your size, feel free to get fitted in-store for accuracy.

How do I know if a bra fits correctly?

A good bra should feel like it’s made just for you - comfortable, supportive, and easy to wear all day. Here’s how to tell if it’s the right fit: The band should fit firmly around your back without riding up. It should sit straight and stay in place - this is what gives you most of the support. The cups should hold your bust gently. No spilling over the top or gaping at the sides - just a smooth, natural shape that feels secure. The straps should rest on your shoulders without digging in or slipping off. You shouldn’t need to keep adjusting them throughout the day. Pro tip: Try moving around - lift your arms, twist, bend. If your bra stays in place and feels good, that’s a great sign.

What are sister sizes in bras?

Sister sizes are bra sizes that have the same cup volume, just balanced differently between the band and the cup. So, if your usual size isn’t fitting quite right - maybe the band feels tight or loose - you might find your perfect match hiding in a size you’ve never considered. Here’s the secret: If you go up a band size, go down a cup size. If you go down a band size, go up a cup size. Example? A 34C, a 32D, and a 36B all share the same cup volume - but the way they hug your body feels different. Still unsure? Find out more with our lingerie fit guide.

Should I size up or down for different bra styles?

Here's a simple style-by-style guide to help you shop with confidence: Push-Up Bras These are made to lift and shape, so they usually have more padding and structure. If the band feels a bit tight, try going up a band size, but stick to your usual cup size to keep that great shape. Bralettes Soft, stretchy and wire-free-—bralettes are all about comfort. If you’re between sizes, go down a size for a snug fit, or stick to your regular size for that relaxed, easy feel. T-Shirt Bras Your everyday favourite! These usually fit true to size, but if there’s a gap at the top of the cup, go down a cup size. If things feel a bit squashed, try a cup size up. Balconette Bras These sit a little lower on your chest and give a lovely lift. The cups can feel smaller, so going up in the cup often gives a better, comfier fit. Plunge Bras Perfect for low-cut tops. These focus on bringing everything together in the centre. If it feels too tight across your chest, try going up a cup size. Full-Coverage or Minimiser Bras These are designed to cover more and offer strong support. They can feel roomier, so you might want to go down a cup size if things feel too loose. Strapless Bras No straps mean the band needs to work harder. These can feel tighter than usual, so it’s often a good idea to go up a band size for more comfort. Sports Bras They’re built to hold everything in place, especially during movement. Compression styles can feel extra snug, so you might prefer to go up a size if you want more breathing room. Wireless Bras No wires, just comfort. These often fit softly. Stick to your usual size, or size down if you want a firmer feel. The best rule? Let your comfort lead the way. Everybody is different, and your bra should work with you - not against you.

What’s the best bra style for small or large busts?

Let’s break it down in a way that makes sense: If you’ve got a smaller bust: Push-up bras give you that extra lift and shape, but only if that’s something you’re after. Bralettes are a dream-—light, soft, no wires, and super comfy for everyday wear. Triangle and plunge styles are also lovely-—especially if you like a more natural shape without too much padding. Our tip: Go with what feels good, not what you think you’re “supposed” to wear. Sometimes less really is more. If you’ve got a larger bust: Full-cup bras give great coverage and hold, especially if you want to avoid spillage. Underwire bras offer more structure and lift-—just make sure the wire sits flat and doesn’t dig in. Minimiser bras help smooth things out under clothing, without flattening or squeezing you. Sports bras with thick straps and a solid band are perfect for keeping things in place when you’re on the move.

Can bras go in the washing machine?

The short answer? Yes, but with a little care. Tossing bras in the machine isn’t a complete no-go, but use a gentle cycle, pop your bra in a mesh laundry bag, and always choose cold water. Skip the harsh spin cycles that can twist wires and flatten padding. And forget about the tumble dryer; air-drying is keeps your bra’s elasticity and fit alive longer. If you want your bra to stick around for the long haul, washing by hand is still the gold standard.

What colours are most versatile when choosing bras?

When it comes to bra colours, some shades just make life easier. They blend in without fuss and work with pretty much everything in your wardrobe. Nude shades are absolute lifesavers - because they basically disappear under light or sheer clothes, giving you a smooth, natural look. Black is a classic for a reason. It’s sleek, flattering, and works perfectly under darker outfits or whenever you want a little extra edge. And if you want something a bit different but still easy to wear, soft grey or gentle blush tones are quietly stylish without stealing the show. The trick is to have a few of these reliable colours in your collection that just works no matter what you’re wearing.

Can I return bras after trying them on?

Yes, you can—as long as the bra hasn’t been worn out or washed and still has the original tags attached. We totally understand that finding the perfect fit sometimes takes a try or two. Here’s the key: when you try it on at home, do it over clean skin (or even over a thin layer like a vest or tee), just to keep it fresh. If it’s not the right fit or feel, simply bring it back with your receipt, and we’ll be happy to help you exchange or return it.
