Custom & Plus Size

Allerton is passionate about creating swimwear that works with your body so that you can be your most confident and comfortable in your swimwear. We incorporate adjustable features into our pieces, and we also offer custom alterations to our valued Allerton Customers.

Plus Sizes

We would love to provide stock on hand for plus sizes although we just aren't able to. If you are curvy we happily make our pieces to order, to any Plus Size. Please just send us an email and let us know what you like. Please allow 1-3 weeks for your piece.

Alteration Options:
  • Altering the back or neck strap length; larger or smaller
  • Changing the width of an underbust or strap – for more support, or less coverage
  • Altering the coverage of the bra or brief – this depends on the style for what is achievable
  • Adding additional loops for adjustable backs
  • Adding clips or clasps, where possible to remove ties
  • Have something else in mind? Let us know! Depending on the alteration, the rate estimate of $35 may vary.

Purchase your alteration from the Allerton Shop, just search Custom Alteration or click here.

Unfortunately we cannot provide refunds on alterations, please make sure you email to discuss your options!

Rate is an estimate and is both additional to the cost of the garment and dependent on your requirements.
