Therefore, the fit differs completely to those of other high street brands and other low end tucking products. Please make sure you measure carefully, following our size guides closely. These can be found on each product page (under the add to card button) The size guides are all below as well.

Underwear

We recommend sizing up if you fall in-between two sizes. The larger size will most likely be the best fit. Of course, there is a small chance this isn’t the case, where we will be happy to cover the cost of return. If you chose to size down first, we do not offer to cover the cost of return.

Bras & Bralettes

If you fall between sizes we recommend you to choose the best option for you. If your weight fluctuates, your breast/chest are still growing we recommend sizing up. If neither of these apply we recommend sizing down.

If you are unsure with your sizing please send us a message here and we would be happy to help.

Kids T-Shirts

Our t-shirts are a relaxed fit. If you fall between sizes we recommend you to choose the best option for you. If you're still growing or your weight fluctuates we recommend sizing up. If neither of these apply we recommend sizing down. The perfect fit of a t-shirt is alway personal to each individual, if you feel you would prefer a size down or up, we are happy to cover the cost of return.

NO! Our flattening/tucking underwear only work if you purchase the exact size stated on our size guides, according to your hip measurement. If you order a size too small, you will struggle to get the garment on and may damage the panty. You will then not be eligible for a return. We cannot stress enough the importance of buying your correct size based on your hip measurement (not waist).

Please do not go off your waist measurement. This will definitely lead you to purchasing the incorrect size. Our panties are designed upon exact hip measurements, therefore you have to measure your hips. Your waist measurement is completely irrelevant.

Not an issue unless they are extra-large. We are working on panties that can work with larger butt implants, without effectively the performance of the panty.

Tucking Underwear

Yes, this is how they are designed. You do not need any other tapes or garments with our panties, although a full tuck is required for optimum smoothness. We are on the way to developing new products where you do not need to tuck, of course these are a secret!

Although, each to their own! Some people wear our panties without tucking, but this is not the intended method. We will not be able to accept a return if you are unhappy with the product without tucking.

Flattening Underwear

You do no have to tuck with our flattening underwear, you simply push everything between your legs and the underwear will hold everything in place.

Kids Briefs

The briefs are designed to flatten the front profile without tucking. We do not feel tucking is necessary and ethical for children's products.

Our underwear goes through a lengthy development and design process to ensure they complete the job set out to do, providing a well-designed product worth its price label. All materials used are personally sourced by Carmen and made for CARMEN LIU and of guaranteed high quality.

There is no specific test or questionnaire which can give you a definite answer. Each person feels differently and has an individual journey to discovering themselves and who they want to be. It is important to learn how to support a child in what can be very distressing times. We can signpost you to relevant, trusted organisations which can help.  

There is help available out there which can offer advice, knowledge, helplines and chat groups on how to respond effectively to the feelings of gender dysphoria or confusion.
