Our flattening/tucking underwear's purpose is completely different to those for cisgender people, for obvious reasons. 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 (above the Add to Cart button). You can also find them below.

Underwear

We recommend sizing up if you fall in-between two sizes. The larger size will most likely be of 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 and Bralettes 

If you fall between sizes we recommend you chose the best option for you. If your weight tends to fluctuate or your breasts/chest are 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 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 chose the best option for you. If you're still growing or your weight fluctuates, we recommend sizing up. If neither of these applies, we recommend sizing down. The perfect fit of T-Shirt is always personal to each individual.

No! Our flattening/tucking underwear only work if you purchase the exact size stated on our size guides, according to your hip measurements. If you order a size too small, you will struggle to get the garment on and may damage yourself and 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 measurements (not waist).

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

Butt implants are not an issue unless they are extra-large. We are working on panties that can work with larger butt implants, without effectiving 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 not 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 table. All materials used are personally sources by Carmen and made for CARMEN LIU and of guaranteed high quality. 

All CARMEN LIU underwear is produced in Europe to ensure high quality in production. Our team work endlessly to bring you the products you need. We perform the final quality checks and packaging inhouse in London to ensure our high standards are met.

This is of course more expensive and time consuming, reflecting in the higher cost of our underwear.

Kids Support Services

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 a very distressing time. We can signpost you to relevant, trusted organisations which can offer support and help. 

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