Beyond comfortable

These bras are soft and comfortable. Once I was introduced to them I wondered why it took me so long to find Subset! I have suffered with ill fitting, expensive, gappy, and poorly made undergarments for years. I am really satisfied with the items I have purchased and I highly recommend to everyone looking for high quality undergarments that fit beautifully!

Thanks for creating excellent products!

Love this Bra

This bra does not disappoint. I have sensitive skin and I am not bothered by it. Now that I know my correct size, I’m going to purchase a few more and throw away all my other bras. Very happy customer!

Comfy but doesn't have sewn pads so my nipples show when I'm cold lol

Love the material. Just wish it came with sewn in pads so I didn't have to be self conscious when I'm cold. Easy to breastfeed my toddler. Just came with a heavy perfume smell but that's why you wash everything.
