We specialise in fuller busted swimwear and ensure that our sizing runs true to size to help you get the correct fit every time. So, we recommend going with your usual size, unless you're between sizes in briefs (i.e. 12-14) and then we suggest you size up. We also recommend sizing up one size in the Serena brief. 

All our styles are designed and fitted on actual women, so we take into consideration the female form when finalising our sizing for each style. We always recommend you try our e-Fitting service to confirm your sizes.

For our bikini briefs - if you’re between sizes, then size up to minimise any cutting in. 

For our bikini tops - depending on the level of coverage you’d prefer, some sizes we’d recommend sizing up. For example, if you’re a size 12E/12F then for the Emelie Bikini Top we’d suggest you size up to a size 12F because it is a busty style. However, for the Ava Bikini Top, we’d suggest you stick with a 12E because it has a deeper cup compared with other styles. 

If you’re not sure, then we suggest both reading the sizing and style advice for each product and sending a quick email to info@marvell-lane.com to quickly double-check.

There are always variations in sizing between different brands, however, we do our best to align our sizing with well-known D+ brands such as Panache or Freya. That being said, our styles are typically designed to be a bustier fit compared with the usual conservative D+ styles, so keep this in mind when trying on our garments.

If you find the fit of your bra perfect - and we mean a nice and firm band (doesn't ride up at the back), underwires sitting flush (or close to flush) against your skin, and no digging in/bulging/gaping - then you can purchase your usual bra size. 

If your dress size is smaller than your bra size (i.e., you're a size 8 dress but wear a 12D bra, or you're a size 12 dress but wearing a 14F bra), then you might be wearing the wrong bra size and should get in touch or try our Fit Quiz. Your bra band should generally not be bigger than your dress size. If you think you’d like to check your sizing beforehand, you can do this via our e-Fitting service or our Fit Quiz.

If you're purchasing a one piece and your bottom half is larger than your top half (i.e. you're a 12F bra and 14 brief), you would try a size 14E to ensure you have a nice fit on both the top and bottom half. If you'd like to confirm this with us, please go through our e-Fitting service.

Many of our bikini tops have adjustable or tie backs - this means that you can purchase your sister size! Specifically for swimwear, all our new styles are being moved to adjustable backs for this reason - sizing up or down in the band, if needed.

We recommend going through our e-Fitting service if you'd like to double check your sizing.

Luckily for you, you’re able to sister size in our swimwear - this means you can purchase a different band size with a similar  up fit (i.e. a size 12E can also fit our 10F or a 14DD). You can see our sister sizing charts here. We generally don't recommend people size up in the band for a sister size - only size down - so send us a quick email or size check so we can help you nail it! 

You can also sign up to our waitlist to be emailed if a particular item is restocked - you’ll find where to do this on the product page under your preferred size. We advise becoming an email subscriber to keep up to date with our upcoming restocks and new collection launches. 

Whilst our styles are not specifically designed to be breastfeeding friendly, many of them allow for easy bust access. Our tops are not only supportive, but the benefit of our swimwear tops specifically is the stretchy fabric means your baby can easily and quickly access your bust for a quick breastfeed.

Our bodies go through so many changes - I mean, you just grew a whole human and now you’re keeping them alive with your breastmilk - which means we should get our bust size professionally checked.

We know it isn’t always possible to head to a specialist for a fitting, so we suggest you try our e-Fitting service and include as much information as possible - i.e. usual dress size, current dress size, current bust size, overbust measurement, and most important, a pic of you wearing your best-fitting bra so we can check the fit. All of this information will allow our team to help guide you. Alternatively, a virtual fitting appointment may also be the best way to go!

Generally, yes. That being said, a few different styles of ours have deeper or shallower cups, and depending on your bust size or your preferred level of coverage, you could fall in between cup sizes. For example, our Emelie and Lola Bikini Tops have shallow cups and are designed to be a busty/revealing fit - some women love this and just order their usual cup size and some women prefer more coverage and size up. It’s best to check your sizing with us if you’re unsure.

Measurements only tell a small part of the story when it comes to establishing a cup size. For example, sometimes people will measure themselves incorrectly or their total measurement indicates they need a larger cup size than they do (because the measurement doesn’t always factor in the back size vs cup size component). 

What we find is that our eFitting service, virtual fitting service, or our Fit Quiz each do a better job of sizing. Unlike with clothing sizes where you can supply one measurement to check if it fits, bra sizing is a combination of cup size and band size and more often than not, we find that people have difficulty measuring this accurately. This in turn causes them to order the incorrect size.

We recommend our e-Fitting service, virtual fitting service or trying our Fit Quiz prior to ordering.

We’ve designed our one pieces to accommodate your bottom half size as well as your bust size. So, when choosing your one piece style, you must factor in the size you are on the bottom half.

Click on our Sister Size Chart here and find your cup size, then slide across to match it to your bottom half size. For example, if you’re a size 10F bra, but wear a size 14 on the bottom half, you will slide across from the 10F up to the 14DD - which is a similar cup size to a 10F but fits like a 14 on the bottom half.

You can go for whatever you feel like! You’re never "too old" for a bikini or one piece. We encourage women to love and embrace their bodies and to wear whatever piece suits their personal style. Again, we recommend going through our e-Fitting service so we can assist with sizing and from here we can recommend sizing for you!

Tying our Chloe top can sometimes be tricky – you can check out how to tie it here. The Chloe top is versatile – you can wear it with a lovely plunge front, or as a backless boat neck for more coverage. 

Our Evie Bra is a plunge style with a lace top edge, whereas the Stella is more of a balconette style with a mesh top edge. The Stella also is lower cut at the sides and has two strap positions on the front of the bra – this helps to hide your straps and band to give you more fashion options!

Our Evie and Stella bras are designed with two straps to give you more fashion options! These bras are designed to only be worn with one set of straps at a time - the skinny ones are for your nice summer dresses and strappy tops. The thicker straps are for every day when your bra isn’t going to be shown. But, our straps are beautifully designed, so a lot of customers want to show them off!
