      Why You 'll Love it

      Feel super confident and comfortable in leggings, pants, skirts and dresses with the AJ shaping underwear.  

      The underwear are designed to provide a level of shaping with clothing on top. We wanted to design a cottony soft pair that is super comfortable.   If you are looking for a more feminine style of underwear, check out the Extra Cute shaping underwear. If shaping is a larger issue for you, we recommend the RUBY Shaping Bikini Bottom.  Many people do wear these under their clothing.

      Size Update: If you have ordered these underwear before August 2023, we have increased them by a 1/2 size.  This is a 1/2" more fabric around the waist.  The feedback was they were running a bit smaller than our swimwear and we wanted to ensure the sizing is more consistent.

      First time ordering RUBIES bottoms? We recommend you use our size guide to get the right fit.

      Size Guide

      Sizing for all RUBIES bottoms should be close to standard US sizing. If it seems far off of what you would have expected, contact us through our chatbot on the bottom left of our website.

      Measure all the way around the waist just under the belly button. Pick the size based on which waist range it fits in.

      If they don't fit, no problem. We will help you select another size and send them out right way. We don’t need to wait for you to return any items.

      If they just don't work out we are happy to accept a return for a full refund.

      How RUBIES shaping products work

      RUBIES shaping products for bottoms such as our shaping underwear, bikini bottoms and one piece are designed to look and feel like regular stylish clothing that cis people are wearing.

      It should not be necessary to tuck or wear our bottoms super tight. Ideally they fit comfortably: not too tight and not too loose.

      Unlike tucking bottoms, they are not intended to completely “hide the bump”. Instead they are designed to convert the pointy area to a more feminine mound. This is why they are extremely comfortable compared to any other products on the market.

      If these are intended for your kiddo who is struggling to feel comfortable in their RUBIES, we gently suggest you educate them how girls or women are not flat there either, rather they are just shaped differently. This can be seen in pictures of cis women and girls wearing leggings.

      RUBIES shaping products for up top such as our bras, bikini top and one-piece have two slits in the chest area that can be used to add multiple inserts like the RUBIES shaping chest pads. This is perfect for those that are experimenting with shaping up top.

      Our tops are made to accommodate a slightly wider torso. Our bra has adjustable straps and clasps. The bra strap is stretchy enough to allow the bra to be put on without using a clasp, as some people new to bras can find this daunting.

      Do not hesitate to reach out to us at hello@rubyshines.com if you have any further questions about how any of our products work or any suggestions about how we can make them even better.

      Fabric and washing instructions

      All our bikini bottoms are made with a combination of nylon and Spandex. All our underwear and bras are made from a combination of polyester and Spandex and our t-shirts are 100% cotton.

      We recommend that you do not use a high heat setting when you put RUBIES products in the wash and dry on a very low heat setting or line dry.

      Great for keeping "skirt tents" away

      Theyre Incredibly well built, the fabric is soft and comfortable. I do have some small nit picks with the waist band not being as elastic as i thought and the edge of the undies in the back gives me a little dimple in my rear. But thats just me being picky. They kept everything in place and prevented some possible exposures during the day.

      Great product

      The underwear I bought for my daughter is amazing. My only complaint is the cost.

      Truly Validating

      Ive tried tucking underwear before and hated it, so this was exactly what I was looking for. It holds everything in place neatly without squeezing or being uncomfortable, while still looking feminine. After I tried on my first pair I immediately bought 3 more, and when they arrived I got rid of all my old underwear. Thanks so much Rubies <3

      Excellent fitting

      These fit just like the guide said they would and work to smooth stuff out down there. I’ve not had any operations, and these do a good job making it less obvious. I love these and want more. I can wear joggers without worrying about things showing up now. I ordered the black sets if that matters

      My daughter feels special!

      Repeat customer!! Thanks to the shaping underwear, bikini and gym shorts from Rubies, my 6yr old daughter can be her best self and immerse into every activity under the sun with her friends. She’s 6yrs and tall for her age with a small-ish waist… the size 8 fits her well (we up-sized from size 6 which became too tight around the waist for her). Thanks for shipping to Australia Xx
